Hi how would you edit this code to redact mutiple words and save the output as a variable?

puts "Enter some text: "
text = gets.chomp

puts "Enter words to redact: "
redact = gets.chomp

words = text.split(" ")
words.each do |word|
if word == redact
print "REDACTED "
print word + " "


Multiple words means giving the program an array of words to redact, so multiple inputs, or one space separated input that can be split into an array.

puts "Enter one or more spaced separated words"
redacts = gets.chomp
redacts = redacts.split()

That means we now have to iterate over the phrase array once for each word in the redacts array, meaning nested .each loops, or another method to see if the word from the phrase is in the redacts array (array.include? comes to mind).

In order to return a list of redacted words which only really makes sense if we want a count since we inputted them, already. If all we want is the list, then return redacts, else build an array and on the return use it to create a histogram.

Something of note about this basic code: It cannot distinguish end in end. or "end", etc. This is a greater challenge to overcome, but first succeed at the initial objective and try to improve once that’s working as expected.
