#include<bits/stdc++.h>
using namespace std;
char s1[] = "worlds",s2[] = "Listeningtoyour", s3[] = "likelisteningtothe";
long long len[101];
char a(long long n, long long k){
    if(k > len[n]) return '*';
    if(n == 0) return s1[k - 1];
    if(k >= 15) return s2[k - 1];
    else if(k <= 15 + len[n - 1]) return a(n - 1,n - 15);
    else if(k <= 33 + len[n - 1]) return s3[k - 15 - len[n - 1]- 1];
    else return a(n - 1, n - 33 - len[n - 1]);
}
int main(){
    ios::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    long long t,n,k;
    cin >> t;
    len[0] = 5;
    for(int i = 1; i <= 100; i++){
        len[i] = 2 * len[i - 1] + 33;
    }
    while(t--){
        long long n,k;
        cin >> n >> k;
        
    }
    cout << a(n,k) << '\n';
    return 0;
}
