Given the following recursive method and function call, how many recursive calls are made, excluding the initial function call? Enter your answer as an integer. public static void mystery (int x, int y) { if (x <= 0) { } System.out.print("cat"); } else if (y < 2) { System.out.print("bat"); mystery (x-1, y); } else { } System.out.print("mat"); mystery (x-1, y-2); mystery (4, 5);

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); }

What is the return value of the function call Comp(3, 4), given the recursive function Comp defined below: int Comp(int a, int b) { if (a + b <= 5) return 2; else return Comp(a-1, b) + Comp(a, b-1); } Question 6 options: 6 10 12 8

The Listed program is about a recursive function named mystery assume the parameter Is never negative and test with several different calls to the function. Explain in sentences what mystery is doing/returning. Explain in higher level what mystery is computing

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.

The solution can be handwritten b) Trace the following recursive method for the function call "isPalindrome(rotator)" and show the output result.

14) What does the following recursive method determine?public boolean question16(int[ ]a, int[ ] b, int j){if(j = = a.length) return false;else if (j = = b.length) return true;else return question16(a, b, j+1);}a) Returns true if a and b are equal in size, false otherwiseb) Returns true if a is larger than b, false otherwise c) Returns true if b is larger than a, false otherwise d) Returns true if a and b have no elementse) Returns the length of array a + length of array b

Write a recursive function that displays a string reversely on the console using the following header: def reverseDisplay(value):For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.

Indirect recursion is when function A calls function B, which in turn calls function A. is it true or false.

Write a recursive algorithm with the following prototype: int add (int x, int y); that returns x if y is 0; and adds x to y otherwise. THE FUNCTION MUST BE RECURSIVE. (hint: the base case should involve a test for y being 0; recursive case should reduce y towards 0)

A recursive method with no base case? 1.causes an infinite loop 2.generates no output 3.does not start 4.all of the answers
