Cоnsider the fоllоwing method, which implements а recursive binаry seаrch.   /** Returns an index in arr where the value x appears if x appears * in arr between arr[left] and arr[right], inclusive; * otherwise returns -1. * Precondition: arr is sorted in ascending order. * left >= 0, right < arr.length, arr.length > 0 */public static int bSearch(int[] arr, int left, int right, int x){  if (right >= left)  {    int mid = (left + right) / 2;    if (arr[mid] == x)    {       return mid;    }    else if (arr[mid] > x)    {       return bSearch(arr, left, mid - 1, x);    }    else    {       return bSearch(arr, mid + 1, right, x);    }  }  return -1;}   The following code segment appears in a method in the same class as bSearch.   int[] nums = {0, 4, 4, 5, 6, 7};int result = bSearch(nums, 0, nums.length - 1, 4);   What is the value of result after the code segment has been executed?
