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

string s1,s2,t;

int main()
{
    int n,i=0,j,sz;
    cin>>n;
    cin>>s1>>t;
    while(1)
    {
        if(s1==t)
        {
            cout<<i<<endl;
            break;
        }
        if(i>=n)
        {
            cout<<"-1"<<endl;
            break;
        }
        s2=s1.at(n-1);
        s1.erase(n-1);
        s2+=s1;
        s1=s2;
        i++;
    }
    return 0;
}


I get time limit -- > Time limit exceeded 8 1.015
Can somebody help me with an idea how to make it run faster ?
