}

#include<iostream> using namespace std; int main(){ char a; cin>>a; cout<<" "<<a<<endl; cout<<" "<<a<<a<<a<<endl; cout<<a<<a<<a<<a<<a<<endl; return 0; }

python的好处：可以一步到位

print(int(int(input())*1024*1024/4))

#include<bits/stdc++.h>
using namespace std;
int main(){
    long long rzr,m;
    cin>>rzr;
    cout<<rzr*1024*256;
}

样例告诉我们了，$1$ MB 答案就是 $262144$，所以我们只需要输出 $262144\times n$ 即可。

python一行解决：

print(int(input())*262144)

是不是很简单（
