Finds the index of a given element in a sorted array using the binary search algorithm.

Algorithm:
1.Declare the left and right search boundaries, l and r, initialized to 0 and the length of the array respectively.

2.Use a while loop to repeatedly narrow down the search subarray, using Math.floor() to cut it in half.

3.Return the index of the element if found, otherwise return -1.

Note: Does not account for duplicate values in the array.
