Problem C
Mörk

Siggi made a machine that can predict the results of football games, but due to being defective it only says how many goals were scored and how many teams scored, never saying which team actually won. Now Siggi needs money so he wants to use his machine to bet on games, but only if he’s sure he’ll win the bet. Siggi can bet on team A winning, team B winning or there being a tie. Can you help him?

Input

The input consists of two lines. The first line contains an integer $n$, the number of goals scored. The second line contains an integer $m$, $0$ if neither team scored, $1$ if only one team scored and $2$ if both teams scored.

Output

Print Jebb if Siggi should bet on the game, Neibb otherwise.
