A given integer num has a hoagie if at least a digit in num is surrounded by two identical digits.

This function takes an integer and returns True is num has a hoagie, False otherwise. Note that

num$//10$ and num$\%10$ will not behave as intended when num is negative, so make sure your

process negative numbers as positive.

Tip: A number that has less than three digits cannot have a hoagie.

$$ You are NOT allowed to type convert num to a string $,$ use lists in any form, add

the digits into a list to traverse or process the number, or to use of the math module
