Reverse a palindrome:

p palindrome

Reverse a string in or not in place

s = ".sdrawkcab si gnirts sihT"
puts s.reverse                             
puts s
s.reverse!                            # => "This string is backwards."
puts s                                # => "This string is backwards."

To reverse the characters means to alter the characters so they read in the opposite direction.

puts "abcdefghijklmnopqrstuvwxyz".reverse
