# Little Jhool and psychic powers

#######################################################################################################################
#
#   Little Jhool always wanted to have some psychic powers so that he could showoff his skills, and magic to people
#   and impress them. (Specially, his girlfriend Big Jhool!) But, in spite all his efforts, hardwork, dedication,
#   Googling, watching youtube videos he couldn't garner any psychic abilities!
#   He knew everyone was making fun of him, so to stop all of that - he came up with a smart plan. Anyone who came
#   to him to know about their future, he asked them to write a binary number for him - and then, he smartly told
#   them if the future for that person had good in store, or bad.
#   The algorithm which Little Jhool follows is, as following:
#       - If the binary number written by the person has six consecutive 0s, or 1s, his future is bad.
#       - Otherwise, he says that their future is good.
#
#   Input format:
#   Single line contains a binary number.
#
#   Output format:
#   You need to print "Good luck!" (Without quotes, and WITH exclamation mark!) if the Jhool is going to tell them
#   that they're going to have a good time. Else, print "Sorry, sorry!" if the person is going to be told
#   that he'll have a hard time!
#
#   Constraints:
#   The binary number will be in string format, with the maximum length being 100 characters.
#
#   SAMPLE INPUT
#   0001111110
#
#   SAMPLE OUTPUT
#   Sorry, sorry!
#
#   Explanation
#   Since the binary number given has six consecutive 1s,
#   little Jhool tells the man that he's going to have a bad time!
