This function takes in a set of integers and a target value, and returns true if there is a pair of integers in the set that sum up to the target value. Otherwise, it returns false.
The candidate's solution is complete and solves the problem. The approach is to use a hash map to store the complement of each number in the array. If the complement exists in the hash map, then a pair exists that sums up to the target value.
