Guys,could you help with that block of coding.
Task is When we find "s", we want Ruby to replace every instance of "s" it finds with "th". We can do this with the .gsub! method, which stands for global substitution.
print "Please input smth"
if user_input.include?( "s")
but the error occurs:
Oops, try again. Make sure you're using .gsub! to replace every 's' with 'th'.
