Write a Python program to determine whether a given year is a leap year.

Hint:$-$ A leap year occurs if the year is divisible by $4.$ However, for century years $($ending in $00),$ it must also be divisible by $400$ to qualify as a leap year.

$-$ For example, years like $400,800,1200,1600,$ and $2000$ are leap years, but $100,200,300,1500,1700,1800,$ and $1900$ are not. Years such as $2004,2008,$ and $2012$ are also leap years.
