Search problems involving combinations and permutations can often be solved using a unified recursive backtracking template. Template Structure Define the output container. Handle input edge cases. Invoke a recursive helper that builds results starting from a given partial solution. Recursive helper...

Problem Description Given an integer array nums with distinct elements, return all possible subsets (the power set). The solution set cannot contain duplicate subsets. You may return the subsets in any order. Example: Input: nums = [1, 2, 3] Output: [[], [1], [2], [1, 2], [3], [1, 3], [2, 3], [1, 2,...
