# TASK #2 > Power Integers
# Submitted by: Mohammad S Anwar
#
# You are given an integer $N.
#
# Write a script to check if the given number can be expressed as mn where m and
# n are positive integers. Otherwise print 0.
#
# Please make sure m > 1 and n > 1.
#
# BONUS: If there are more than one ways to express the given number then print
# all possible solutions.
#
# Example 1:
# For given $N = 9, it should print 32 or 3^2.
#
# Example 2:
# For given $N = 45, it should print 0.
#
# Example 3:
# For given $N = 64, it should print all or one of 8^2 or 2^6 or 4^3.
