Subsets
Explore how to generate all possible subsets of a given array of unique integers, including the empty set. Learn to handle constraints and avoid duplicate subsets while implementing your solution in a coding environment.
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:
-
nums.length -
nums[i] - All the numbers of
numsare unique.
Examples
Understand the problem
Let’s take a moment to make sure you’ve correctly understood the problem. The quiz below helps you check if you’re solving the correct problem:
Subsets
Find all subsets for the given set.
nums = [6, 7, 8]
[[], [6], [7], [8], [6, 7], [6, 8], [7, 8]]
[[], [6], [7], [8], [6, 7], [6, 8], [7, 8], [6, 7, 8]]
[[], [6], [6, 7], [6, 8], [7, 8], [6, 7, 8]]
[[6], [7], [8], [6, 7], [6, 8], [7, 8], [6, 7, 8]]
