Write a Ruby program to test whether a year is leap year or not.

Ruby Code:

year = [2012, 1500, 1600, 2020]
year.each do |y|
  if y % 400 == 0
  	 puts y.to_s + ' is leap year'
    elsif y % 4==0 && y % 100 != 0 
      puts y.to_s + ' is leap year'
  else  puts y.to_s + ' is not leap year'
  end
end

Output:

2012 is leap year
1500 is not leap year
1600 is leap year
2020 is leap year
