This problem is about finding all possible permutations of a set of distinct integers. For example, if the input is [1, 2, 3], then the output should be [[1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]].

A.I. Evaluation of the Solution

The candidate's solution is complete and solves the problem. The approach is recursive and uses a backtracking algorithm. The time and space complexity of the solution is O(n!).
