# Beware! Today's exercise, which derives from an interview question asked at
# Facebook, is trickier than it looks:
#
# You are given an array of integers. Write a program that moves all non-zero
# integers to the left end of the array, and all zeroes to the right end of the
# array. Your program should operate in place. The order of the non-zero
# integers doesn't matter. As an example, given the input array
