code:

/**

• Note: The returned array must be malloced, assume caller calls free().
  /
  int twoSum(int* nums, int numsSize, int target, int* returnSize)
  {
  int i, j;

  returnSize = (int *)malloc(sizeof(int) * 3);

  for(i = 0; i<numsSize; i++)
  {
  for(j = 0; j<numsSize; j++)
  {
  if(nums[i] + nums[j] == target)
  {
  returnSize[0] = i;
  returnSize[1] = j;
  return returnSize;
  }
  }
  }
  return returnSize;
  }

I dont understand why I cant pass the test example input.
