Ruby program to check Palindrome Number

Write a Ruby program to check Palindrome Number

Palindrome Number: If the number is equal to it's reversed number, then the given number is a palindrome number. For example: 121 is a palindrome number while 122 is not.

class PalindromeNumber

  def checkPalindrom

     print "Enter the number: "

     input_num = gets.chomp.to_i

     num = input_num

     new_num = 0 

     while num > 0 do

       rem = num % 10 

       num = num / 10 

       new_num = (new_num * 10) + rem 

     end

     if input_num == new_num

       print "#{input_num} is a palindrome number"

     else 

       print "#{input_num} is not a palindrome number"

     end 

  end

end

p = PalindromeNumber.new 

p.checkPalindrom

Output:

Enter the number:  1221
1221 is a palindrome number
