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≤
nums.length ≤10
- −10≤
nums[i] ≤10
- All the numbers of
nums are unique.
Problems such as this one, where we need to find all possible subsets of a given set, can be efficiently solved using the subsets pattern. This pattern involves generating all possible subsets of a given set by using binary representations of indices to represent which elements should be included in each subset. This approach allows us to solve a wide range of problems that involve generating all possible subsets of a set.
