For Ruby -> Collection -> Letter frequency counter

Question

how can we make it so it will print / puts only the letters that exist in the phrase and not all the alphabet?
what if statement shall we use? i thought and tried something like the one that has the question following this lesson but it didn't work.
thanks to whom ever will help. :-)

Answer 1

freqs ={}
freqs.default = 0
text = "I like Ruby, this is my favorite on Sololearn!!"
text.each_char { |char| freqs[char] += 1}

puts freqs
