玩够了，看下面，是正确答案

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

int main(){
    string a;
    cin >> a;
    for(int i = 0;i < a.size();i++){
        cout << a[i];
    }
    return 0;
}

如果不小心玩没了，看下面

#include<bits/stdc++.h>
using namespace std;
int a[10];
int main(){
	string n;
	cin >> n;
	if(n == "1"){
		cout << 1;
	}else if(n == "2"){
		cout << 1;		
	}else if(n == "3"){
		for(long long i = 1;i <= 1e17;i++){
			cout << "1" << endl;
		}
	}else if(n == "4"){
		cout << " 4";	
	}else if(n == "5"){
		return -1;	
	}else if(n == "6"){
		while(1){}
	}else if(n == "waaaaaaaaaaaaaaaaaaaaaaaaaaaa"){
		while(1){n+=n;}
	}else{
		cout << n;
	}
	return 0;
}
