Looping through 2 arrays

Ruby
1

I’m trying to loop through 2 arrays, and notice some odd behaviour,
probably because the syntax is not correct

unsorted.each do |x|
sorted.each do |y|
puts 'this is que_words ’ + x + ‘.’
puts 'this is s_words ’ + y + ‘.’
end
end

I added the ‘puts’ in as I’m trying to build a bigger block of code
and trying to take it one step at a time with some checking in place.
unsorted has elements, sorted is empty.

When I run the above, nothing is output. When I comment out the
sorted loop, unsorted outputs it’s elements. Would having an empty
array effect the output of unsorted or is this just plain wrong ?

If sorted is empty it, never enters the sorted.each block, which is
where all the output is. Try this

unsorted.each do |x|
puts 'this is que_words ’ + x + ‘.’
sorted.each do |y|
puts 'this is s_words ’ + y + ‘.’
end
end

Okay …thanks! makes sense.
Apologies also for leaving the que_words and s_words in the puts
statement.
I meant to change them out since unsorted and sorted are easier to
understand.
