Write a function that converts any integer up to 3999 to its complement in Roman numerals.

Implement def integer_to_roman(num):, accepting an integer from 1 through 3999 and returning a string. For example, 58 returns LVIII, and 1994 returns MCMXCIV.

Constraints

Return the canonical Roman numeral representation.
Use subtractive notation for 4, 9, 40, 90, 400, and 900.
