class Solution {public:vector<vector<int>> subsetsAnswer;//globle variable.vector<vector<int>> subsets(vector<int>& nums){sort(nums.begin(),nums.end());vector<int> partOne;findsubsets(partOne,0,nums);return subsetsAnswer;}void findsubsets(vector<int> partOne,int i,vector<int>& nums){//这个递归就不太明白了?if(i==nums.size()){subsetsAnswer.push_back(partOne);return;}else{findsubsets(partOne,i+1,nums);partOne.push_back(nums[i]);findsubsets(partOne,i+1,nums);}}};

如果有不对，请多多指正！
