# TASK #1 > Strobogrammatic Number
# Submitted by: Mohammad S Anwar
# A strobogrammatic number is a number that looks the same when looked at upside
# down.
#
# You are given two positive numbers $A and $B such that 1 <= $A <= $B <= 10^15.
#
# Write a script to print all strobogrammatic numbers between the given two
# numbers.
#
# Example
# Input: $A = 50, $B = 100
# Output: 69, 88, 96
import sys
A, B = map(int, sys.argv[1:3])
out = []
