用java进行的尝试

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class tina{

    public static void main(String[] args){

     Scanner myScanner = new Scanner(System.in);

     int count=myScanner.nextInt();

     int sum1=0,sum2=0,sum3=0;

     for(int i=1;i<=count;i++){

         int num=myScanner.nextInt();

         switch(num){

         case 1:sum1++;break;

         case 5:sum2++;break;

         case 10:sum3++;break;

         }

      }

     System.out.println(sum1);

     System.out.println(sum2);

     System.out.println(sum3);

  }  

}
