InputThe first line of the input contains an integer T(1 <= T <= 100) which means the number of test cases.In every case first input two integers M(0<=M<=30) and N(0<=N<=30),N represent the number of babies a couple borned,then in the follow line are N binary numbers,0 represent girl,and 1 represent boy.OutputForeach test case you should output the total money a couple have to pay for their babies.

Sample Input2

2 5

0 0 1 1 1

2 2

0 0

Sample Output

70000 RMB

0 RMB

#include<stdio.h>

int main()
{
 int nn[31];
 nn[0] = 1;
 for (int i = 1; i < 31; i++)
 {
  nn[i] = nn[i - 1] * 2;
 }
 int datanum;
 scanf("%d", &datanum);
 while (datanum--)
 {
  int num[2] = { 0 };
  int n, m,num1,sum;
  scanf("%d%d", &n, &m);
  for (int i = 0; i < m; i++)
  {
   scanf("%d", &num1);
   num[num1]++;
  }
  int k;
  if (num[0] <= n)
  {
   k = num[1];
  }
  else
  {
   k = num[0] + num[1] - n;
  }
  sum = nn[k] - 1;
  if (sum == 0)
  {
   printf("0 RMB\n");
  }
  else
  {
   printf("%d0000 RMB\n",sum);
  }
 }
 return 0;
}

整体思路就是找到罚款的人数。
