思路：排序就可以得到中間數，然後總和和中間數*n比較一下即可

代碼：

#include <cstdio>#include <cstring>#include <cmath>#include <algorithm>using namespace std;const int N = 1005;int n, a[N], sum;int main() {    while (~scanf("%d", &n)) {sum = 0;for (int i = 1; i <= n; i++) {    scanf("%d", &a[i]);    sum += a[i];}sort(a + 1, a + n + 1);if (a[(n + 1) / 2] * n > sum) printf("YES\n");else printf("NO\n");    }    return 0;}
