Web Reference: In-depth solution and explanation for LeetCode 78. Subsets in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official and forum solutions. After the recursive call returns (meaning it has explored all possibilities with the number included), we **remove** that number from our current subset. This "backtracking" allows us to explore the path where the number was *not* included, enabling us to generate all possible combinations. Subsets - Given an integer array nums of unique elements, return all possible subsets (the power set). The solution set must not contain duplicate subsets. Return the solution in any order.
