【Leetcode】1.两数之和

C++版:

class Solution {
public:
    vector twoSum(vector& nums, int target) {
      int i,j;
      vector s;
      for(i=0;i 
 python版：
 
class Solution(object):
    def twoSum(self, nums, target):
        """
        :type nums: List[int]
        :type target: int
        :rtype: List[int]
        """
        n = len(nums)
        for x in range(n):
            for y in range(x+1,n):
               if(nums[x]+nums[y]==target):
                   return x,y
