Given nums = [2, 7, 11, 15], target = 9,Because nums[0] + nums[1] = 2 + 7 = 9,return [0, 1].

Answer：

int* twoSum(int* nums, int numsSize, int target) {int j, i;int *test = NULL;test = (int )malloc(2*sizeof(int)); for (i=0; i<numsSize ;i++){  for (j=i+1; j<numsSize ;j++){   if(nums[i]+nums[j] == target){    *(test) = i;    *(test+1) = j;    }  } } return test;}
