只有30分，到底是哪里出现了问题啊QAQ

#include <stdio.h>
#include <string.h>

int main()
{
	char a[10000];
	int count = 0,x = 0,y = 0;
	while((a[count] = getchar()) != 'E')
	{
		while(a[count] == 'W' || a[count] == 'L')
			count++;
		//if(count % 25 == 0)	getchar();//消耗换行符 
	}
	
	//11分制： 
	for(int i = 0;i < (count / 11)+1;i++)
	{
		x = 0;
		y = 0;
		for(int j = i * 11;j < 11*(i+1);j++)
		{
			if(a[j] == 'W')	x++;
			if(a[j] == 'L')	y++;
		}
		printf("%d:%d\n",x,y);
	}
	printf("\n");
	
	//21分制： 
	for(int i = 0;i < (count / 21)+1;i++)
	{
		x = 0;
		y = 0;
		for(int j = i * 21;j < 21*(i+1);j++)
		{
			if(a[j] == 'W')	x++;
			if(a[j] == 'L')	y++;
		}
		printf("%d:%d\n",x,y);
	}
	return 0;
