A exercise to overwrite ruby count helper method

letter_count.rb

def letter_count(words, letter)
  if words.include?(letter)
    count = words.count(letter)
    puts "The letter #{letter} appears #{count} time(s)"
  else
    puts "The letter #{letter} did not appear in '#{words}'"
  end
end

# test

letter_count("Should I kill myself, or have a cup of coffee?", "E")
letter_count("Should I kill myself, or have a cup of coffee?", "e")
letter_count("Should I kill myself, or have a cup of coffee?", "x")
letter_count("Should I kill myself, or have a cup of coffee?", "X")

## returns

# The letter E did not appear in 'Should I kill myself, or have a cup of coffee?'
# The letter e appears 4 time(s)
# The letter x did not appear in 'Should I kill myself, or have a cup of coffee?'
# The letter X did not appear in 'Should I kill myself, or have a cup of coffee?'



# another solution which also works for and down case letters

def letter_count(words, letter)

letter = letter.downcase
times = words.to_s.count(letter)
  if times == 0
    puts "The letter #{letter} did not appear in '#{words}'"
  else
    puts "The letter #{letter} did appear #{times} times(s) in #{words}"
  end
end

# test

letter_count("Should I kill myself, or have a cup of coffee?", "E")
letter_count("Should I kill myself, or have a cup of coffee?", "e")
letter_count("Should I kill myself, or have a cup of coffee?", "x")
letter_count("Should I kill myself, or have a cup of coffee?", "X")

## returns

# The letter e did appear 4 times(s) in Should I kill myself, or have a cup of coffee?
# The letter e did appear 4 times(s) in Should I kill myself, or have a cup of coffee?
# The letter x did not appear in 'Should I kill myself, or have a cup of coffee?'
# The letter x did not appear in 'Should I kill myself, or have a cup of coffee?'
