代码实现：

#include<stdio.h>int main()
{int N, D;double e, mayemp = 0, emp = 0;scanf("%d %lf %d", &N, &e, &D);for (int i = 0; i < N; i++){int K, cnt_less = 0, cnt_more = 0;scanf("%d", &K);double *ele = (double*)malloc(sizeof(double)*K);for (int j = 0; j < K; j++){scanf("%lf", &ele[j]);if (ele[j] < e)cnt_less++;else if (ele[j] > e)cnt_more++;}if ((double)cnt_less > (double)K / 2 && K <= D)mayemp++;else if ((double)cnt_less > (double)K / 2 && K > D)emp++;}printf("%.1f%% %.1f%%", mayemp / N * 100, emp / N * 100);return 0;
}
