"""Gapful Numbers

A gapful number is a number of at least 3 digits that is divisible by the number formed by the first
and last digit of the original number.

Input: 192  Output: true (192 is gapful because it is divisible 12)

Input: 583  Output: true (583 is gapful because it is divisible by 53)

Input: 210  Output: false (210 is not gapful because it is not divisible by 20)

Write a program to check if the user input is a gapful number or not.

Bonus: Print all the gapful numbers in a given range.

---------------Important-----------------------
If you want a range, enter the lower and the upper bound separated by a space.
example:
100 200

If you just want to check for a number, just input your number.
example:
120
