Leap Year Lister Using Two Dimensional Arrays in Ruby

Write a program using a two-dimensional array that will ask how many numbers of years to be processed and then the program will ask the user to give a series of years.  The program will check and determine which of the given year is a leap year or not a leap year and display the results on the screen.
