题解：读懂题意按照题意模拟。。。

熟悉了一个库函数，strstr，memcpy

#include
     
      #include
      
       int main(){    int N;    char str[150];    int cnt[3] = {
   0};    scanf("%d",&N); getchar();    for(int j = 0; j < N; j++){        gets(str);        if(strstr(str,"black")&&strstr(str,"blue")) cnt[0]++;        else if(strstr(str,"white")&&strstr(str,"gold")) cnt[1]++;        else cnt[2]++;    }    double sum = cnt[0] + cnt[1] + cnt[2];    printf("%.10lf\n%.10lf\n%.10lf",cnt[0]/sum*100,cnt[1]/sum*100,cnt[2]/sum*100);    return 0;}
