The binary search algorithm returns the index of the target value if it exists in the array, or -1 if it does not.

A.I. Evaluation of the Solution

The candidate's solution is a binary search, which is the optimal solution for this problem. The time complexity of a binary search is O(log n), which is better than the time complexity of a linear search, which is O(n). The candidate's solution correctly returns the index of the target value if it exists in the array, or -1 if it does not.
