# TASK #1 > Divide Integers
# Submitted by: Mohammad S Anwar
#
# You are given two integers $M and $N.
#
# Write a script to divide the given two integers i.e. $M / $N without using
# multiplication, division and mod operator and return the floor of the result
# of the division.
#
# Example 1:
# Input: $M = 5, $N = 2
# Output: 2
# Example 2:
# Input: $M = -5, $N = 2
# Output: -3
# Example 3:
# Input: $M = -5, $N = -2
# Output: 2
