The problem is testcase 5 is not working but the other test cases are working but all i know is that test case 5 should be "quiet". In my code snippet i cannot see any error at all.

Answer 1

Yes 30 is ok

you can do this to init char array and be sure of length:

#include <iostream>
#include <cstring>
using namespace std;

int main() {

string in;
cin>>in;
int size = in.length();
char floor[size];
strcpy(floor, in.c_str());

// your code

Answer 2

I think Input length greater than 20.
so not enough size

Answer 3

Answer 4

It worked i think the issue was the size
