Character Counting

### 1. Tells the Numbers of Characters
def count_letters(string)
  array = string.delete(" ").split("")

  hash = Hash.new(0)
  array.each do |letter|
    letter = letter.downcase
    hash[letter] += 1
  end
  puts hash.inspect
end

count_letters("This is a stupid string that I'm using")

### 2. Returns the indice positions of characters
def count_indices(string)
  array = string.delete(" ").split("")

  hash = Hash.new { |hash,key| hash[key] = []}
  array.each_with_index do |letter, index|
    hash[letter.downcase.to_sym] << index
  end
  puts hash.inspect
end 

count_indices("This is a stupid string that I'm using")
