Subsets– LeetCode Problem

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]]

Constraints:

  • 1 <= nums.length <= 10
  • -10 <= nums[i] <= 10
  • All the numbers of nums are unique.
Subsets– LeetCode Solutions
Subsets in C++:
class Solution {
 public:
  vector<vector<int>> subsets(vector<int>& nums) {
    vector<vector<int>> ans;

    dfs(nums, 0, {}, ans);

    return ans;
  }

 private:
  void dfs(const vector<int>& nums, int s, vector<int>&& path,
           vector<vector<int>>& ans) {
    ans.push_back(path);

    for (int i = s; i < nums.size(); ++i) {
      path.push_back(nums[i]);
      dfs(nums, i + 1, move(path), ans);
      path.pop_back();
    }
  }
};
Subsets in Java:
class Solution {
  public List<List<Integer>> subsets(int[] nums) {
    List<List<Integer>> ans = new ArrayList<>();

    dfs(nums, 0, new ArrayList<>(), ans);

    return ans;
  }

  private void dfs(int[] nums, int s, List<Integer> path, List<List<Integer>> ans) {
    ans.add(new ArrayList<>(path));

    for (int i = s; i < nums.length; ++i) {
      path.add(nums[i]);
      dfs(nums, i + 1, path, ans);
      path.remove(path.size() - 1);
    }
  }
}
Subsets in Python:
class Solution:
  def subsets(self, nums: List[int]) -> List[List[int]]:
    ans = []

    def dfs(s: int, path: List[int]) -> None:
      ans.append(path)

      for i in range(s, len(nums)):
        dfs(i + 1, path + [nums[i]])

    dfs(0, [])

    return ans

  190. They love the buzz and enticement of the gameplays as opposed to the thrill of winning or losing real cash. What are penny slots? These are slots that allow you to bet the lowest denominations of currency such as pennies or cents. Nickel slots are one step above penny slots. Each spin will cost 5c per payline. Each spin of a slot with nine pay lines and all active lines will cost you $0.45.Although you might burn through your bankroll five times faster than with penny slots, the payouts are still 5x better. Although nickel slots were once top-rated in land-casual casinos, they are less common today. By increasing your coin size in online casinos, many penny slots can easily be converted to nickel slots. Going for free penny slots no downloads preserves your budget and prepares you for big games for real money in the future. But it is not enough to punt confidently and securely:
