Write a Python program that accepts a year written as a four-digit Arabic (ordinary) numeral and outputs the year written in Roman numerals.

Roman numerals are V for 5, X for 10, L for 50, C for 100, D for 500, and M for 1,000.
Recall that some numbers are formed by using a kind of subtraction of one Roman “digit”; for example, IV is 4 produced as V minus I, XL is 40, CM is 900, and so on.
A few sample years: MCM is 1900, MCML is 1950, MCMLX is 1960, MCMXL is 1940, MCMLXXXIX is 1989.
(Hints: Use division and mod.)

Assume the year is between 1000 and 3000.

If ana decided to be against in prioritizing the task in her to do list, she will likely have insufficient time in doing the things in which she wouldn't be able to finish and in the same way, she won't be able to finish all of the task that she needed to do.

Well first we would need the actual diagram. perhaps you missed it?
