我在本题中用getline 读入证词，在本机上（用的noilinux）去掉最后一个字符，输出看起来还是正常的，但与其它字符串匹配不上。

在洛谷上必须要去掉才能过

洛谷的测评环境不是 linux 吗

代码：

#include<bits/stdc++.h>
using namespace std;
int m,n,p;

int spkr[105],fake[25],err,ans;
inline void update(int who,int is){
	if(fake[who]*is==-1)err=1;
	else fake[who]=is;
}
int main(){
	scanf("%d%d%d",&m,&n,&p);
	for(int i=1;i<=m;i++)cin>>name[i];
	for(int i=1;i<=p;i++){

		getline(cin,say[i]);

	}
	for(int day=0;day<7;day++){

	}
	if(!ans)puts("Impossible");
	else cout<<name[ans];

	return 0;
