Exercise 1: Check Leap Year

Problem statement

Write a leap_year? method that takes a year (a number), and determines if it’s a leap year.

Example

leap_year?(2000)
leap_year?(2020)
leap_year?(2022)
leap_year?(2100)

This should print out:

true
true
false
false

Recall that a leap year meets two qualifications:

• It’s divisible by four.
• It’s not divisible by 100 unless it’s divisible by 400.

Note: You just need to provide the definition of the method, and it will be automatically evaluated on the given input value.
