This problem asks us to return all possible subsets of a given set of distinct integers. For example, if the input is [1,2,3], then the output should be all possible subsets of those integers: , [1,2], [1,2,3], [1,3], , [2,3], and .
A.I. Evaluation of the Solution
The candidate's solution is complete and solves the problem. The approach is to generate all subsets by iterating through the input array and adding each element to all existing subsets.
