For the binarysearch method in section 7.10.2, what is low and high after the first iteration of the while loop when invoking binarysearch(new int[]{1, 4, 6, 8, 10, 15, 20}, 11)? a. low is 0 and high is 6b. low is 5 and high is 5c. low is 3 and high is 6d. low is 4 and high is 6e. low is 6 and high is 5

Answer D : Low is 4 and high is 6

Explanation:

Here is Function

int binarySearch(int arr[], int l, int r, int x)  {

 while (l <= r) {  

       int m = l + (r - l) / 2;  

  // Check if x is present at mid  

       if (arr[m] == x)  

           return m;  

  // If x greater, ignore left half  

       if (arr[m] < x)  

           l = m + 1;  

  // If x is smaller, ignore right half  

       else

           r = m - 1;   }  

    // if we reach here, then element was  

   // not present  

   return -1; }
