这题比较水，没仔细想就写出来了

代码

  1. #include<cstdio>
  2. #include<vector>
  3. #include<algorithm>
  4. using namespace std;
  5. int main(){
  6.     int n, temp, sum = 0, halfsum = 0;
  7.     scanf("%d", &n);
  8.     vector<int> num(n);
  9.     for(int i = 0; i < n; i++){
  10.         scanf("%d", &num[i]);
  11.         sum += num[i];
  12.     }
  13.     sort(num.begin(), num.begin() + n);
  14.     for(int i = 0; i < n/2; i++){
  15.         halfsum += num[i];
  16.     }
  17.     printf("%d %d", n % 2, sum - 2 * halfsum);
  18.     return 0;
  19. }
