i'm really confusing by getting this verdict, i'm pretty sure in my skill so i think problem in compiler, isnt it?

#include<iostream>

using namespace std;
 int main() {
 string s;
 cin >> s;
 for(auto now : s) cout << 1;
}

Maybe I'm an addict, but since n<=5e6<2^24 I used unsigned short + unsigned char in order to immitate 3 byte integer type.

If you have TLE on 9 and you are using Palindomic tree, You should write cin/cout
with "ios_base::sync_with_stdio (false);" instead of scanf/printf
