Given a list of integers and a target sum, this problem determines whether any two integers in the list sum to the target sum. For example, given the input [1, 2, 3 , 4, 5] and target sum = 9, the output would be true because 4 + 5 = 9.
The candidate's solution is correct and demonstrates a level of completeness. The solution uses a hash table to store the values of the array, which allows for checking if the complement of the current value is in the hash table. If it is, then the candidate has found a pair that sums to the target sum. The solution has a time complexity of O(n) and a space complexity of O(n).
