typed goodbye to quit the program. The first part is done the problems
is that how can i find the longest word?
example:
Type a word (or goodbye to quit): Hello
Type a word (or goodbye to quit): Hello Hello
Type a word (or goodbye to quit): goodbye

The longest word is “Hello Hello”

Hello,

p "Longest is #(longest)"

You need accolades and not parenthesis here.
Also, 'puts' might be better in this case ('p' uses 'inspect' and will
display the string between "..")

puts "Longest is #{longest}"

Cheers,

Change p "Longest is #(longest)" with
puts "Longest is #(longest) of size #{longest.size}"
