- Can you help me with this program?In C++Write a program that finds all the ways in which the mouse can move to the cheese, and if any, display it with ‘*’.An example diagram of the task is shown in the figure: Operating instructions: Compose a recursive function path (int i, int j), receiving as parameters the coordinates of the current position of the mouse (initially 0.0, and then run with parameters (i-1, j), (i + 1, j), (i, j-1) or (i, j + 1)).Problem: Recursive Power Method Design a python function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output. Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00Write a C program that compute the perimeter of Circle, Rectangle, Triangle and Square. The program asks the user to specify the shape as follows: C for Circle, S for Square, R for Rectangle and T for Triangle and then it reads the required value to compute the perimeter for that specified shape. Note: the perimeter for the shapes:????l? = ? × ?????? × ?S????? = ? × ????????????? = ? × (????? + ??????) ???????? = ????? + ????? + ????3
- Consider the following function: public void bSearch(int[] A, int value, int start, int end) { if (end value) { return bSearch(A, value, start, mid); } else if (value > A[mid]) { return bSearch(A, value, mid+1, end); } else { return mid; } } The mutation program P' changes the part as shown below. } else if (value > A[mid]) { return bSearch(A, value, mid+2, end); } else { return mid; } A test input is given t1: {A = [2, 3, 5, 7, 10, 11], value = 6, start=0, end=5}. Which statement below best describes the mutant with regards to the test input? O a. t1 resolves mutant P O b. The mutant P' with regards to test input t1 is live.Write a function which takes two integer parameters for values to be added together and returns the result by value. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Assume that the values passed to the function will not be negative, but could be 0 or positive, and will both be integers. The function must implement addition recursively, and cannot use the standalone + operator (only ++) or call any other functions.5. Write a python function that takes one integer parameter, makes sure it is an integer, prints sum of every two digits and return the sum of digits from the number entered by the user up to 1, using recursion. Sample input: 4 Sample output: 4+3 = 7 7+2 = 9 9+1 = 10
- language: Python Problem: Write a function log2(x), which gives an integer approximation of the log base 2 of a positive number x, but it does so using recursion. Use a base case where you return 0 if x is 1 or less. In the general case, add 1 to the answer and divide x by 2. On top of writing the function, also write a test case for the function to prove the program works.in C++ please 1. Write a recursive function called sumover that has one argument n, which is an unsigned integer. The function returns a double value, which is the sum of the reciprocals of the first n positive integers. (The reciprocal of x is the fraction 1/ x .) For example, sumover(1) returns 1.0 (which is 1/1); sumover(2) returns 1.5 (which is 1/1 + 1/2); sumover(3) returns approximately 1.833 (which is 1/1 + 1/2 + 1/3). Define sumover(0) to be zero. Do not use any local vari- ables in your function. Submit output for when n=290 2. isPal funcitonImplement the recursive function isPal(), which determines whether a string str isa simple palindrome. A simple palindrome is a string consisting entirely of thecharacters a-z that reads the same forward and backward. For instance, theupcoming are palindromes: dad, level, mom, madamimadam,gohangasalamiimalasagnahog.Use the following declaration of isPal():bool isPal (const string& str, int startIndex, intendIndex);It returns true…Write these in Pseudocode #1a – In pseudocode, write a call to a function that passes 1 Integer variable and 1 Integer array, and saves a Boolean value in return. #1b – In pseudocode, write the function that accepts 1 Integer and 1 Integer array and returns a Boolean. In the function, search the Integer array with a for-loop, and if the Integer parameter is found in the array, return false. If the Integer parameter is not found, return true. #2a – In pseudocode, write a call to a module that passes 1 Integer variable, 1 Real variable, 1 String constant, and 1 String literal as arguments. #2b – In pseudocode, write the module header that accepts 1 Integer, 1 Real, and 2 Strings as parameters. #3 – This pseudocode has multiple problems. Fix the calling statement and the definition below so that the routine accepts 3 grades as parameters and returns the average into a variable.…
