差两个点，怎么调都不对了，求调……

#include <bits/stdc++.h>
using namespace std;

bool check(char ch)

	switch(ch)
	{

			return 1;
		default: return 0;
	}
}

int main()
{
	cin >> s >> t, n = s.size(), s = ' '+s, t = ' '+t;
	if(s.size() != t.size()) {printf("No"); return 0;}
	for(int i = 1; i <= n; i++) 
		if(s[i] != '@') bs[s[i]-'a']++;
		else sc++;
	for(int i = 1; i <= n; i++) 
		if(t[i] != '@') bt[t[i]-'a']++;
		else tc++;
	for(int i = 0; i < 25; i++)
		if(bs[i] > bt[i])
