7. Cornered!
Attention again soldier!
Our men have been cornered by the enemy and we need to save them or else this mission will fail.
The first thing we need to do is to identify them, the ones cornered by the enemy! LET'S MOVE!
Instructions:
Ask the user for an integer input which represents the total number of men we have in the field. Then, ask the user for the numbers of each of the men. Finally, ask the user for two numbers which represents the enemies who have cornered our men.Then, print all the numbers of our men who have been cornered by the enemy (i.e. the numbers that are in between the two numbers of the enemy).Input
1. Total number of men
2. Numbers of the men
3. First number of the enemy
Constraints
This is guaranteed to be lesser than the second number of the enemy
4. Second number of the enemy

- Python Programming Part 2 Direction: Use PYTHON to solve this problem. Description: This part tests for two things. The program must identify all resistors in series or in parallel with each other and calculate the equivalent resistance for each group of resistors. Recall that total resistance of resistors in series are added up while the total conductance of those in parallel are added up. Input Format: The first line of the input consists of 1 integer N which is the total number of resistors. The next N lines will consist of 3 strings and an integer R each separated by a space. The first string is the resistor name, the second and third strings are the node names where the resistor terminals are connected, and R is its resistance value. Output Format: One line for each group of resistors in series or parallel. Each line starts with a list of resistors arranged in lexicographical order (see Lexicographic order - Wikipedia) followed by their total resistance rounded off to the nearest…arrow_forward(Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros).

Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The maximum is 3.0The minimum is -1.0The average is 1.25arrow_forward(Find the two highest scores)Write a program that prompts the user to enter the number of students and each student’s name and score, and displays the name and score of the student with the highest score and the student with the second-highest score.Sample RunEnter the number of students: 5Enter a student name: SmithEnter a student score: 60Enter a student name: JonesEnter a student score: 96Enter a student name: PetersonEnter a student score: 85Enter a student name: GreenlawEnter a student score: 98Enter a student name: ZhangEnter a student score: 95Top two students:Greenlaw's score is 98.0Jones's score is 96.0arrow_forward
- "NEED ONLY CODE NO EXPLANATION" Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output. Input: 4 2 2 Output 4arrow_forward(Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a. Sample Run Enter x1 and y1: 1.5 -3.4 Enter x2 and y2: 4 5 The distance between the two points is 8.764131445842194arrow_forward(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise notarrow_forward

- (Geometry: point in a circle?) Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure 3.7a.(Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is 2(x2 - x1)2 + (y2 - y1)2. Test yourprogram to cover all cases.) Two sample runs are shown below: Enter a point with two coordinates: 4 5Point (4.0, 5.0) is in the circleEnter a point with two coordinates: 9 9Point (9.0, 9.0) is not in the circlearrow_forwardPut code as well as code with outputarrow_forward(Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game. Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock. The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.arrow_forward
