Question

Implement a recursive java method to find the sum of the first n int's in a java int array. Max size 20.

Answer 1

Solution:

public class SumOfArray {

private int[] a;

private int n;

private int result;

   public int sumOfArray(int[] a,int n) {

     this.a = a;//Max size is 20

     n = a.length;

     if (n == 0)  // base case

     return a[n];

     else

         return a[n] + sumOfArray(a, n-1);

     return result;

  } // End SumOfArray method

} // End SumOfArray Class
