Grokking the Coding Interview Patterns in C#

Subsets

Explore how to find all unique subsets of an integer array in C#. Learn to generate subsets including the empty set while avoiding duplicates. This lesson helps you understand the problem constraints and implement efficient solutions using core coding patterns.

We'll cover the following...

Statement

Given an array of integers, nums, find all possible subsets of nums, including the empty set.

Note: The solution set must not contain duplicate subsets. You can return the solution in any order.

Constraints:

  • 1≤1 \leq
