I have been trying to pass this exercise for a long time and am getting frustrated- I really need help. Here’s my code.
text = gets.chomp
words = text.split
frequencies = Hash.new(0)
words.each { frequencies[word] += 1}
frequencies = frequencies.sort_by { |k, v| v }
frequencies.reverse!
frequencies.each do |word, frequency|
puts word + " " + frequency.to_s
end
Hello! I just passed this exercise being frustrated as well.
The code I used is as follows:
puts “Text:”
text = gets.chomp
words = text.split(" ")
frequencies = Hash.new(0)
words.each { |element| frequencies[element] += 1 }
frequencies = frequencies.sort_by {|a, b| b}
frequencies.reverse!
frequencies.each do |word, frequency|
puts word + " " + frequency.to_s
end
The only difference I can see between yours and mine is the line: words.each { frequencies[word] +=1}
Maybe try declaring a variable inside of words.each so you can add to the array like I do?
It still didn’t work but thanks anyway.
It worked when I left the editor blank. I think Codecademy has issues.
This got me through but I don’t think it was really what they were asking for.
puts “How about a sentence?:”
text = gets.chomp
words = text.split(" ")
frequencies = Hash.new(0)
words.each { |word| frequencies[word] += 1 }
frequencies.each { |word,frequency| puts
word + " " +frequency.to_s}
What mean “.to_s”? My code was correct but it didn’t work till I wrote that. I don’t remember to read it in previous lessons, I’ve passed becouse I saw your comment so, thanks for that.
Here is my code (if it minds) ↓
puts "Enter your text here please: "
text = gets.chomp
words = text.split(" ")
frequencies = Hash.new(0)
words.each { |w| frequencies[w] += 1 }
frequencies.each { |w, f| puts w + " " + f.to_s }
It seemed to be the frequency.reverse! that made mine stick.
Once I took frequency.reverse! out, it worked perfectly, though laneeverhart is right, that’s not what codecademy asked or implied we should do.
Same here. It worries me that a website to teach programming has bugs in their code lol.
This works for me. Try this:
text = gets.chomp
puts text
words = text.split()
frequencies = Hash.new(0)
words.each do |word|
puts frequencies[word] += 1
end
frequencies = frequencies.sort_by do |words, count| count end
frequencies.reverse!
frequencies.each do |word, count|
puts "#{word} #{count}"
end.to_s means “to string”.
The variable f in the above code is an integer, and you can’t concatenate integers to strings (i.e. you can’t stick numbers to strings). For example
puts "hello " + “world” <— prints “hello world”
puts "hello " + 5 <— doesn’t work because 5 is not a string
puts "hello " + “5” <— prints “hello 5”
puts "hello " + 5.to_s <— prints “hello 5” (first converts 5 to “5”, then concatenates)
It would help if the example was actually related to what you were doing at the time… whoever designed this ruby unit is no teacher that’s for sure!
