Question

Consider the following definition of a recursive method. public static int mystery(int[] list, int first, int last) { if (first == last) return list[first]; else return list[first] + mystery(list, first + 1, last); } Given the declaration int[] alpha = {1, 4, 5, 8, 9}; What is the output of the following statement? System.out.println(mystery(alpha, 0, 4));

Answer 1

Output:

27

Step-by-step explanation:

Here, in the following function of the recursion in tha Java Programming Language.

• Define a function "mystery()" and pass two integer type argument and one integer array type argument.
• Set the if statement and check condition is the variable "first" is equal to the variable "last" then, return the first element of the array.
• Otherwise, it returns the addition of first to the last element and then again.
