print "What's uuuup?"
user_input = gets.chomp
if (user_input.downcase.include? "s") || (user_input.downcase.include? "ce") || (user_input.downcase.include? "ci") 
  user_input.gsub!( /[sS]/ , "s" => "th" , "S" => "TH")
  user_input.gsub!( /ce/ , "the" )    
  user_input.gsub!( /Ce/ , "The" )  
  user_input.gsub!( /CE/ , "THE" )  
  user_input.gsub!( /ci/ , "thi" ) 
  user_input.gsub!( /Ci/ , "Thi" )  
  user_input.gsub!( /CI/ , "THI" )  
  print "Your string is #{user_input}"
elsif user_input.empty?
  puts "Try again"
  puts "No letters to change, try again"

:white_check_mark: Add an additional if statement to re-prompt the user for input if they don’t enter anything

:white_check_mark:Think about how you might account for words in which the letter “c” sounds like an “s”
(Solved-ish. But I wanted to see if there could be a way to solve it using one line of .gsub

user_input.gsub!( /[sc]/ , "th")

If you the user writes “I’m fine, come on!” , the result is “No letters to change, try again”, which is fine.
However, if the user writes “I’m super fine, Cecilia! come on!” , the result is "I’m thuper fine, thethilia! thome on!"

So, I tried writing:

user_input.gsub!( /[scei]/ , "s" => "th" , "ce" => "the" , "ci" => "thi")

But for some reason it doesn’t allow substituting a sequence of more than one character? Like it allows:
"s" => "loremipsum" but the other way around it returns nil
The result is "I’m thuper fine, cilia! comeon!"

:white_check_mark:Think about how you might preserve the user’s original capitalization
I tried to do something with .casecmp but I couldn’t come up with anything :cold_sweat:
I’m not 100% happy about this, cause I feel like there could be a better way of writing this.
Maybe having a way to say substitute “c” to “th” with the exception of when it comes after “-a”, “-o” and “-u”?

If anyone knows a way around this, please let me know!
