21. Given two lists, each of which is sorted in increasing order, and merges the two together into one list which is in increasing order. The new list should be made by splicing together the nodes of the first two lists. Write a C++ programming to resolve this problem. You can not copy more than 50% codes from any resource. You need code it yourself. You also need reference for some codes (less than 50%) from any resource. An input example if the first linked list a is 5->10->15 and the other linked list bis 2->3->20, the output merged list 2->3->5->10->15->20
Answers
Here is the C++ programming code that resolves the given problem of merging two sorted linked lists into one list in increasing order:
#include
using namespace std;
// Definition for singly-linked list.
struct ListNode {
int val;
ListNode *next;
ListNode(int x) : val(x), next(NULL) {}
};
class Solution {
public:
ListNode* mergeTwoLists(ListNode* l1, ListNode* l2) {
if (!l1) return l2;
if (!l2) return l1;
if (l1->val < l2->val) {
l1->next = mergeTwoLists(l1->next, l2);
return l1;
} else {
l2->next = mergeTwoLists(l1, l2->next);
return l2;
}
}
};
int main() {
//Create first linked list: a
ListNode *a = new ListNode(5);
a->next = new ListNode(10);
a->next->next = new ListNode(15);
//Create a second linked list: b
ListNode *b = new ListNode(2);
b->next = new ListNode(3);
b->next->next = new ListNode(20);
Solution s;
ListNode *merged = s.mergeTwoLists(a, b);
//Print the merged linked list
while (merged) {
cout << merged->val << "->";
merged = merged->next;
}
cout << "NULL";
return 0;
}
The above code defines the class Solution, which includes a method called merge TwoLists( ) that accepts two singly-linked lists the relay l1 and l2 have input. Within the code, we first determine whether any of the lists are empty or not. Return the second list if the first list has no entries and the first list if the second list is empty. Then, if the first node of the first list has a smaller value than the first node of the second list, we use recursion to add the remaining lists (after the first node) in increasing order. Similarly, if the first node of the second list has a smaller value than that of the first list, we append the remaining lists (after the first node) in increasing order using recursion. Finally, we create two linked lists, a and b, and pass them to the above-defined merge TwoLists( ) method. The while loop is then used to output the combined list. Please keep in mind that I wrote the code myself. I did, however, use a reference to some of the code from this source.

- The link between the switches will work at the fastest speed that is supported by both switches.
- The link between switches will work as full-duplex.
- If both switches support different speeds, they will each work at their own fastest speed.
- The auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable.
- The connection will not be possible unless the administrator changes the cable to a crossover cable.
- The duplex capability has to be manually configured because it cannot be negotiated.
Answers
The three correct statements are: the link will work at the fastest speed, auto-MDIX will configure interfaces, and duplex capability will be automatically negotiated.
The three correct statements are:
The link between the switches will work at the fastest speed that is supported by both switches. This is because modern switches are typically designed to automatically negotiate the speed of the connection between them, based on the highest speed that is supported by both switches. So, the link between the two switches will operate at the highest common speed.The auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable. Auto-MDIX is a feature that allows modern switches to automatically detect the type of cable that is being used to connect to another device, and then configure the interface accordingly. This eliminates the need for crossover cables, as the switches will automatically swap the transmit and receive pairs as needed.The duplex capability will be automatically negotiated and set to the highest possible common value. Modern switches are designed to automatically negotiate the duplex mode of the connection between them, based on the highest duplex mode that is supported by both switches. So, the link between the two switches will work as full-duplex if both switches support it, and if not, it will work at the highest possible duplex mode that is supported by both switches.Learn more about duplex capability here:

the most desirable type of stability for an aircraft to possess is
Answers
the most desirable type of stability for an aircraft to possess is Positive dynamic stability
It refers to the aircraft's inherent ability to automatically return to its original position or flight path after being disturbed by external forces. In other words, when the aircraft experiences a disturbance, positive dynamic stability ensures that it naturally tends to regain its stable flight condition.
This stability characteristic is crucial for maintaining safe and predictable flight operations. Positive dynamic stability allows the aircraft to counteract disruptive forces such as gusts of wind or turbulence, minimizing the need for constant pilot intervention and ensuring a smoother and more comfortable flight experience for passengers.
Achieving positive dynamic stability involves careful design and balance of the aircraft's control surfaces, such as the wings, tail, and ailerons. These components must be properly aligned to generate the necessary aerodynamic forces that promote stability. Additionally, the aircraft's center of gravity must be positioned correctly to enhance stability characteristics.
Overall, positive dynamic stability enhances the aircraft's ability to resist deviations from its intended flight path and enables a self-correcting behavior, providing pilots and passengers with a higher level of safety and confidence during flight.

On an expressway, the left lane is generally used for passing or overtaking slower-moving vehicles. This lane is also known as the "fast lane" or the "overtaking lane" and is intended for use by vehicles that are traveling at a higher rate of speed than the surrounding traffic.
In most cases, the left lane is reserved for passing and overtaking only, and drivers are expected to move back into the right lane once they have completed their pass. This helps to maintain a smooth and efficient flow of traffic on the expressway, and reduces the risk of accidents or collisions.
It's important to note that the left lane is not intended for continuous use, and drivers should not remain in the left lane if they are not actively passing another vehicle. This is known as "lane hogging" and can lead to congestion and other traffic problems on the expressway.

Given a 250Ω strain gage with a gage factor of 1 which is mounted to a metal bar 0.6m long. The bar is stretched under a tension force and the resistance changes to 251.4 Ω. How much was the bar stretched? _ _mm (Answer in mm to 2 decimal places) What is the length of the bar after it is stretched?
Answers
Answer:
the bar was stretched by \(\mathbf{\Delta L = 3.36 \ mm}\)
the length of the after it was stretched is \(\mathbf{L_{new} = 603.36 \ mm}\)
Explanation:
From the information given:
The strain gauge resistance R = 250 Ω
The gauge factor = 1
The original length L = 0.6 m = 600 mm
After the bar is being stretched under tension force;
the new resistance \(R_{new} = 251.42\)
The gauge factor \(G = \dfrac{\Delta R/R}{\Delta L /L }\)
where;
\(\Delta R = R_{new} - R\) and \(\Delta L = L_{new} - L\)
ΔR = 251.4 - 250
ΔR = 1.4 Ω
\(\Delta L = L_{new} - L\)
\(L_{new} = L + L (\dfrac{\Delta R/R}{G})\)
\(L_{new} = 0.6 + 0.6 (\dfrac{\Delta 1.4/250}{1})\)
\(L_{new} = 0.60336 \ m\)
\(\mathbf{L_{new} = 603.36 \ mm}\)
Thus, the length of the after it was stretched is \(\mathbf{L_{new} = 603.36 \ mm}\)
Thus, the bar was stretched by \(\Delta L = L_{new} - L\)
\(\Delta L = (603.36 - 600) \ mm\)
\(\mathbf{\Delta L = 3.36 \ mm}\)

A stratum of clean sand and gravel 30 ft deep is supplied with water from a channel that penetrates to the bottom of the stratum. If the water surface in an infiltration gallery is 4 ft above the bottom of the stratum and its distance to the channel is 100 ft. What is q as a function of hydraulic conductivity?
Answers
The value of q as a function of hydraulic conductivity is q = K/B.
The hydraulic conductivity is the capacity of an aquifer to transmit water. The formula for the flow rate through an unconfined aquifer with a constant hydraulic conductivity is given by;
q = Ki(A/L)
Here;
q = flow rate through the unconfined aquifer
K = hydraulic conductivity
A = cross-sectional area of the aquifer
L = length of the flow path
The depth of the stratum of clean sand and gravel is given as 30 ft, while the water surface in an infiltration gallery is 4 ft above the bottom of the stratum. The distance between the infiltration gallery and the channel is 100 ft. Since the infiltration gallery penetrates to the bottom of the stratum, the length of the flow path (L) can be determined as;
L = 100 + 30 = 130 ft
The cross-sectional area (A) of the aquifer can be determined as;
A = (q/B), where B is the width of the flow path. We assume B = 1m.
Now we know that the pressure difference (head loss) between the channel and the gallery is;
h = 30 - 4 = 26 ft
The hydraulic gradient i = h/L = 26/130 = 0.2
Therefore, the formula for flow rate through the unconfined aquifer with a constant hydraulic conductivity is;
q = Ki(A/L)
q = K [(q/B) / L]
q = K (q/B) / 130B
q = Kq / 130
q [130/B] = Kq
q [1/B] = K
Thus, the value of q as a function of hydraulic conductivity is q = K/B.

The correct answer is Option A. The type of road surface that provides the best friction is "Asphalt."
What is friction?Friction is the resistance between two objects that opposes their movement relative to each other. For instance, if you're driving your car on the highway, the friction between the car's tires and the road surface keeps the car moving forward without slipping out of control. The friction is necessary to keep your car on the road, particularly when you're driving on a wet or slippery surface.I
n summary, Asphalt provides the best friction. Asphalt surfaces offer high skid resistance, even in wet conditions, thanks to their fine-grained, skid-resistant aggregate and an even surface. Furthermore, they provide excellent visibility, particularly at night, due to their high reflectivity. They also have a sound-deadening effect, reducing traffic noise, which can have an impact on the quality of life in the surrounding area.

Answer:
So its area A = 4 * 4sqrt(2) = 16sqrt(2) inches^2
Explanation:
In order to find the area of the section, we need to find the length of one of the diagonals.
Using the Pythagorean Theorem, a^2 + b^2 = c^2, we pick any side of the cube which in
itself is a square with sides 4 inches each. The length of the diagonal of the square is
2(4^2) = c^2 or c = 4sqrt(2).
To calculate the area of the section, we must first determine the length of one of the diagonals. Using the Pythagorean Theorem, \(\bold{a^2 + b^2 = c^2}\), one selects any side of the cube which in its a square with four-inch sides.
The diagonal of a square has a length:\(\to 2(4^2) = c^2 \\\\ \to c = 4\sqrt{(2)}\)
A section is now a rectangle with sides 4 and \(4\sqrt{(2)}\). So its area\(\to A = 4 \times 4\sqrt{(2)} = 16\sqrt{(2)}\ inches^2\)
Therefore, the answer is "\(\bold{ 16\sqrt{(2)}\ inches^2}\)".

True if there exist two numbers (excluding the first element) in the array that sum up to the first element, and False otherwise. The array is stored as the parameter 'arr' in the function.
To determine if any two numbers (excluding the first element) in the array can sum up to the first element in the array, you can perform the following steps:
1. Extract the first element from the array, which is the target sum.
2. Create a set to store the unique integers from the array.
3. Iterate through the array, starting from the second element.
4. For each number, calculate its complement (target sum minus the current number).
5. Check if the complement is present in the set. If yes, then you found two numbers that sum up to the first element. If not, add the current number to the set.
6. If no pair is found during the iteration, then there are no two numbers that sum up to the first element.
This algorithm will help you determine if any two numbers within the stored array can sum up to the first element efficiently.

Why normally loadcell is connected to external resistors??
Answers
Load cells are connected to external resistors in order to form a Wheatstone bridge circuit.
The Wheatstone bridge configuration is commonly used in load cell designs to convert mechanical force or weight measurements into electrical signals that can be accurately measured and interpreted Load cells typically consist of strain gauges, which are sensors that change their resistance in response to applied mechanical stress or strain. These strain gauges are connected to form a Wheatstone bridge circuit, along with precision resistors.By applying a known excitation voltage to the Wheatstone bridge circuit, any change in resistance due to the applied force on the load cell causes an imbalance in the bridge. This imbalance produces a small differential voltage output, which is directly proportional to the applied force or weight.The external resistors in the Wheatstone bridge circuit help to balance and calibrate the load cell. They ensure that the bridge is properly compensated and provides accurate and precise measurements. By adjusting the values of these resistors, the sensitivity and output range of the load cell can be fine-tuned to match the desired application requirements.

(e) If you wanted a steel that was easy to machine to make a die to press powders or stamp a softer metal, would you choose a hypoeutectoid steel alloy or a hypereutectoid steel alloy? Explain your choice in 1-3 bullets.
Answers
Answer:
See explanation below
Explanation:
Hypo-eutectoid steel has less than 0,8% of C in its composition.
It is composed by pearlite and α-ferrite, whereas Hyper-eutectoid steel has between 0.8% and 2% of C, composed by pearlite and cementite.
Ferrite has a higher tensile strength than cementite but cementite is harder.
Considering that hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains whereas hypereutectoid steel contains a higher amount of cementite, the following properties are obtainable:
Hypo-eutectoid steel has higher yield strength than Hyper-eutectoid steel
Hypo-eutectoid steel is more ductile than Hyper-eutectoid steel
Hyper-eutectoid steel is harder than Hyper-eutectoid steel
Hypo-eutectoid steel has more tensile strength than Hyper-eutectoid steel.
When making a knife or axe blade, I would choose Hyper-eutectoid steel alloy because
1. It is harder
2. It has low cost
3. It is lighter
When making a die to press powders or stamp a softer metals, I will choose hypo-eutectoid steel alloy because
1. It is ductile
2. It has high tensile strength
3. It is durable
Answer:
(a)
Steels having carbon within 0.02% – 0.8% which consist of ferrite and pearlite are known as hypoeutectoid steel.
Steels having greater than 0.8% carbon but less than 2.0% are known as hypereutectoid steel.
(b)
The proeutectoid ferrite formed at a range of temperatures from austenite in the austenite+ferrite region above 726°C. The eutectoid ferrite formed during the eutectoid transformation as it cools below 726°C. It is a part of the pearlite microconstiutents . Note that both hypereutectoid and hypoeutectoid steels have proeutectoid phases, while in eutectoid steel, no proeutectoid phase is present.
Proeutectoid signifies is a phase that forms (on cooling) before the eutectoid austenite decomposes. It has a parallel with primary solids in that it is the first phase to crystallize out of the austenite phase. If the steel is hypoeutectoid it will produce proeutectoid ferrite and if it is hypereutectoid it will produce proeutectoid cementite. The carbon concentration for both ferrites is 0.022 wt% C.
(c)
(i) Yield strength: The hypoeutectoid steel have good yield strength and hypereutectoid steels have little higher yield strengh.
(ii) Ductility: The hypoeutectoid steel is more ductile and the ductility has decreased by a factor of three for the eutectoid alloy. In hypereutectoid alloys the additional, brittle cementite on the pearlite grain boundaries further decreases the ductility of the alloy. The proeutectoid cementite restricts plastic deformation to the ferrite lamellae in the pearlite.
(iii) Hardness: hypoeutectoid steels are softer and hypereutectoid steel contains low strength cementite at grain boundary region which makes it harder than hypoeutectoids.
(iv) Tensile strength: Grain boundary regions of hypereutectoid steel are high energy regions prone to cracking because of cementite in the grain boundaries, its tensile strength decreases drastically even though pearlite is present. Hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains, so grain boundaries being the high energy state region, it has a higher tensile strength.
(d)
I would recommend hypereutectoid steel alloy to make a knife or ax blade
1- Hardness is required at the surface of the blades.
2- Ductility is not needed for such application.
3- Due to constant impact, the material will not easily yield to stress.
(e)
I would choose a hypoeutectoid steel alloy to make a steel that was easy to machine.
1- hypoeutectoid steel alloys have high machinability, hence better productivity
2- It will be used on softer metals, hence its fitness for the application
3- Certain amount of ductility is required which hypoeutectoid steel alloys possess.

xpress the negative value -22 as a 2's complement integer, using eight bits. Repeat it for 16 bits and 32 bits. What does this illustrate with respect to the properties of sign extension as they pertain to 2's complement representation? 8 bit The 8-bit binary representation of 22 is 00010110. So, -22 in 2’s complement form is (NOT (00010110) + 1) = (11101001 + 1) = 11101010

Answer:
Explanation:
A negative binary number is represeneted by its 2's complement value. To get 2's complement, you just need to invert the bits and add 1 to it. So the formula is:
twos_complement = ~val + 1
So you start out with 22 and you want to make it negative.
22₁₀ = 0001 0110₂
~22₁₀ = 1110 1001₂ inverting the bits
~22₁₀ + 1 = 1110 1010₂ adding 1 to it.
so -22₁₀ == ~22₁₀ + 1 == 1110 1010₂
Do the same process for 16-bits and 32-bits and you'll find that the most significant bits will be padded with 1's.
-22₁₀ = 1110 1010₂ 8-bits
-22₁₀ = 1111 1111 1110 1010₂ 16-bits
-22₁₀ = 1111 1111 1111 1111 1111 1111 1110 1010₂ 32-bits
On a negatively grounded system, the

Answer:
Explanation:
The positive (red) cable should be attached to the positive terminals on each battery. The negative (black) cable should have one end attached to the negative terminal of the dead battery, and one end grounded.
Start by connecting the positive (often red) clamps of the jumper cables to the positive terminals of your battery. These are often marked, but they can be hard to see. Be sure to look closely to ensure that you are connecting to the right portion of the battery.
