Create a function that returns the smaller number.
Examples
smaller_num("21", "44") ➞ "21"
smaller_num("1500", "1") ➞ "1"
smaller_num("5", "5") ➞ "5"
Notes
- Numbers will be represented as strings, and your output should also be a string.
- If both numbers tie, return either number.
- Numbers will be positive.
- Bonus: See if you can do this without converting to integers.
