# Life, the Universe, and Everything

#######################################################################################################################
#
#   Your program is to use the brute-force approach in order to find the Answer to Life, the Universe, and Everything.
#   More precisely... rewrite small numbers from input to output. Stop processing input after reading
#   in the number 42. All numbers at input are integers of one or two digits.
#
#   SAMPLE INPUT
#   1
#   2
#   88
#   42
#   99
#
#   SAMPLE OUTPUT
#   1
#   2
#   88

n = int(input().strip())

while n != 42 :
