This challenge is quite simple. You will take an input which will be a year from 1801 to 2400, and output if it is a leap year or not.
Your input will have no newlines or trailing spaces:
You will output in any way that you like that clearly tells the user if it is or isn't a leap year (I will accept y or n for yes/no)
You can get a list of leap years here: http://kalender-365.de/leap-years.php I would note that leap years are not ever four years always. 1896 is a leap year, but 1900 is not. The years that follow this "skip" are:
1900 2100 2200 2300
1936 -> y 1805 -> n 1900 -> n 2272 -> y 2400 -> y
EDIT: This is based on a standard Gregorian calendar: http://www.epochconverter.com/date-and-time/daynumbers-by-year.php
