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

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

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

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

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.

puts "Text to search through: "
text = gets.chomp
puts "Words to redact "
redact = gets.chomp

text.downcase!
redact.downcase!

words = text.split(" ")

words.each do |letters|
 if redact.include? letters
   print "REDACTED "
 else
   print letters + " "
 end
end
  • What could you do to make sure your redactor redacts a word regardless of whether it’s upper case or lower case? :white_check_mark:

  • How could you make your program take multiple, separate words to REDACT? :white_check_mark:
    In the beginning I was overthinking it, trying to think about using nested .each. And also finding different ways of comparing arrays:

matches = words & redacted
no_matches = words - redacted

matches.each do |letters|
  print "REDACTED "
end
no_matches.each do |redacted|
  print redacted + " "
end

# However I couldn't manage the way to print the result in the right order.

#=>Text to search through:
#=>Hello my name is
#=>Words to redact:
#=>Hello name
#=>REDACTED REDACTED my is

Turns out using .include? waaaaay simpler. I can’t believe it took me so long to figure this out.:scream:

  • How might you make a new redacted string and save it as a variable, rather than just printing it to the console? :poop:
    I could only save it as a local variable result.
words.each do |letters|
 if redact.include? letters
   x = "REDACTED "
 else
   y = letters + " "
 end
  result = "#{x} #{y}"
  print result
end

If anyone knows how to do this last bit, please let me know

#6

The problem with the include? method above is it will not differentiate between any words that partly make up the word.

For example entering the following:

Text input: This is my text,
&
Words to redact: this my

Will yield:
REDACTED REDACTED REDACTED text.

Why? Because “is” is included in “this” even though it isn’t our target word.

#7

We will need to see your exact code in order to reach a conclusion. Please post in a reply.

Second exercise : * How could you make your program take multiple, separate words to REDACT?

puts “Write a sentence:”
text = gets.chomp
puts “what do you want to delete from this text?”
redact = gets.chomp

words = text.split(" “)
twowords = redact.split(” ")
#censor = 0

words.each do |word|
twowords.each do |twoword|
if word.downcase == twoword.downcase
#print "CENSORED "
censor = 1
end
end
if censor == 1
print "CENSORED "
censor = 0
else
print word + " "
end
end
