Given an array of integers, the "Two Sum" problem is to find the indices of two numbers in the array that add up to a given target. There is always a unique solution to this problem.

A.I. Evaluation of the Solution

The candidate's solution is correct and demonstrates a level of completeness. The solution uses a dictionary to store the values of the array and uses the dictionary to check if the complement of the current value is in the dictionary. If it is, then the indices of the complement and the current value are returned. The time complexity of this solution is O(n) because the dictionary is iterated through once. The space complexity of this solution is O(n) because the dictionary is the same size as the array.
