leetcode 两数之和：为什么输入结果是半个括号

Question

我把代码块写在了系统提供的函数里，但结果显示输出错误

/**
 * Note: The returned array must be malloced, assume caller calls free().
 */



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