ruby - Finding the most occurring character/letter in a string -

trying occurring letter in string.

so far:

puts "give me string" words = gets.chomp.split counts = hash.new(0) words.each |word|   counts[word] += 1 end

does not run further asking string. doing wrong?

rather getting count word word, can process whole string immediately.

  str = gets.chomp   hash = hash.new(0)   str.each_char |c|     hash[c] += 1 unless c == " " #used filter space   end

after getting number of letters, can find letter highest count with

max = hash.values.max

then match key in hash , you're done :)

puts hash.select{ |key| hash[key] == max }

or simplify above methods

hash.max_by{ |key,value| value }

the compact form of :

  hash = hash.new(0)   gets.chomp.each_char { |c| hash[c] += 1 unless c == " " }   puts hash.max_by{ |key,value| value }
