Task

Define a function int_to_roman that takes one parameter:

Name	Type	Example Input	Constraint
input_num	int	3000	The integer should be between 1 and 4999 inclusive.

When called, the function should return the input number converted to a roman numeral.

Remember to meet the following constraints of roman numerals:

1. You can only use the Roman numerals I, V, X, L, C, D and M, no other characters or notation is allowed.
2. You must follow the traditional rule of Roman numeral formation where smaller numerals are placed before larger numerals to indicate subtraction. For example, 4 is represented as IV, not IIII.
