Subsets
TIME: O(n * 2^n)
SPACE: O(n)
Problem Statement
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.
Real Engineering Applications
In production systems, this concept directly maps to caching index layers, route lookups optimizations, compiler scope parsing validations, and multi-thread dependency schedulers.
