用gets（）为啥会CE啊= = 代码如下：

#include<iostream>
#include<cstdio>
#include<cstdlib>
#include<cstring>
#include<algorithm>
#include<map>
#include<stdio.h>
#define ll long long

bool op=1;

inline ll read()

	c=getchar();
	while(c<'0'||c>'9')
	{
		if(c=='-')
			f=-1;
		c=getchar();
	}
	while(c>='0'&&c<='9')
	{
		num=num*10+c-'0';
		c=getchar();
	}
	return num*f;
}
int main()
{
	n=read();
	for(int i=1;i<=n;i++)
	{
