string functions

Hi to all !
I am trainee on RoR. I did not know how to use string functions? Please
help me.I am waiting for your positive response.

The String class has methods associated with it. You use these the same
way as most methods in Ruby:

s = 'a string'

s.upcase
#=> "A STRING"

s.reverse
#=> "GNIRTS A"
