Subsets
Problem
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.
Example 1:
Input: nums = [1,2,3] Output: [[],[1],[2],[1,2],[3],[1,3],[2,3],[1,2,3]]
Example 2:
Input: nums = [0] Output: [[],[0]]
Pseudocode
- don't understand question
Solution
// from solutions
let result;
var subsets = function (nums) {
result = []; // no need this if function is executed once
recursive(0, nums, []);
return result;
};
var recursive = function (start, nums, subset) {
// console.log(subset)
result.push(subset.slice(0));
for (let i = start; i < nums.length; i++) {
subset.push(nums[i]);
// console.log(subset)
recursive(i + 1, nums, subset);
subset.pop();
// console.log(subset)
}
};
