Trace the following recursive method for the function call "isPalindrome(rotator)" and show the output result

Use ONLY PyCharm, please.Thank you.

What is the return value of the function call Comp(4, 5), given the recursive function Comp defined below: int Comp(int a, int b) { if (a + b <= 6) return 3; else return Comp(a-1, b) + Comp(a, b-1); }

Using recursive functions in Python, given three letters in the alphabet, get their permutations together with the combinations of any two letters from it.

Write a recursive function called Rev takes a string argument (str) and and integerargument(i – the initial string position). Rev prints the str in reverse. You may not useany built-in reverse function or method. You may use string’s length method.

Write a recursive function (Java) called Fac which takes one positive integer argument (n) and returns n! You may not use a built-in factorial method or function.

Determine the output of the following recursive function when n = 64. (show your working/steps) int func (int n) { if (n ==1) return 0 else return 2 + func ( ) }

Hi can check my code below and see whether it has meet the following, if not kindly assist and correct it for me. a). Recursive function in Java that accepts an integer as input and returns 1 + 1/2 + 3 + 1/4 + ...(n or 1/n). b). The answer is the sum of the odd integers from 1 to n plus the sum of the reciprocals of the even integers. Thank you. public class Main {public static double sum(int n) {if (n <= 0) {return 0;} else if (n % 2 == 0) {return 1.0 / n + sum(n - 1);} else {return n + sum(n - 1);}}public static void main(String[] args) {System.out.println(sum(5));}}

T/F 9. As loop variables and recursive solutions are also not used for iterative solutions, the recursive solution generally makes memorization more effective (use fewer stored) than the corresponding iterative solution.

•rewrite calculateSum function as a recursive function. m(i) = m(i-1) + i/(i+1), where i >=1
