Subject: Re: use reqex to get the middle character and repeat it

# In this situation the string will always be 3 chars long and 

this is not regex :)

irb(main):007:0> RUBY_VERSION
=> "1.9.0"
irb(main):008:0> str='qxq'
=> "qxq"
irb(main):009:0> str[0]+str[1]*4+str[2]
=> "qxxxxq"

or more succinct,

irb(main):010:0> str[1]*=4
=> "xxxx"
irb(main):011:0> str
=> "qxxxxq"
