I’m learning to program and came across Chris P.'s Ruby Tutorial.
I’ve got to the Array and Iterators chapter (
and the following assignment " Let’s write a program which asks us to
type in as many words as we want (one word per line, continuing until
we just press Enter on an empty line), and which then repeats the
words back to us in alphabetical order. OK? "
****** HOWEVER I’m not allowed to use the .sort method ********
The covered chapters (1 ~ 7) have not covered method creation,
Classes, Blocks or Procs, so the challenge is to solve the assignment
without using them ( which is dandy since I don’t know what they are
and I want to solve this assignment before I move forward to discover
what they are).
This is what I’ve come up with so far, however when run… It’s not
working - surprise surprise.
Could someone initially give me an idea of what is going wrong rather
than rectify my code.
puts ‘Type in as many words as you want and once you’ve had enough,
just ‘enter’ a clear line.’
words_array = 
input = gets.downcase.chomp
break if input.empty?
words_array << input
wordCheck = words_array.last
rotateCounter = 0
sortedWords_array = 
until words_array.length == 0
while rotateCounter <= words_array.length
if words_array >= wordCheck
words_array.push words_array.shift rotateCounter = rotateCounter + 1 else wordCheck = words_array rotateCounter = 0 end end sortedWords_array.push wordCheck until wordCheck = words_array.last words_array.push words_array.shift end words_array.pop rotateCounter = 0 wordCheck = words_array.last
