Problem A
Eldspýtur

Benni and Óðinn are playing a game. In the game they start with $n$ matches and take turns, with Benni always going first. In each round, one is allowed to remove between $1$ and $k$ matches. The one who removes the last match wins. Benni and Óðinn are super smart so if they can win, they will. Benni is a very sore loser and won’t play unless he wins. Given that both of them play perfectly, will Benni be willing to play?

Input

The input is a single line containing two integers $n$ and $k$, the number of matches at the start of the game and the maximum number of matches one may remove in a single move.

Output

Print Jebb if Benni is willing to play, print Neibb otherwise.
