Here's the defination of leap year:

A year will be a leap year if it is divisible by 4 but not by 100. If a year is divisible by 4 and by 100, it is not a leap year unless it is also divisible by 400.

Try to implement a method to see if a given year is leap year.

is_leap_year?(2014) # false
is_leap_year?(2000) # true

isLeapYear(2014) # false
isLeapYear(2000) # true

IsLeapYear(2014) //false
IsLeapYear(2000) //true
