### Solution 01

from sys import stdin

M,D=map(int,input().split())

S=(M*2+D)%3

def fortune(x):

    return {0:'普通',1:'吉',2:'大吉'}.get(x)

print(fortune(S))

### Solution 02

from sys import stdin

arr = [int(x) for x in stdin.readline().split()]

def sum_arr(arr):

    return (arr[0]*2 + arr[1])%3

def fortune(x):

    return {0:'普通',1:'吉',2:'大吉'}.get(x)

print(fortune(sum_arr(arr)))
