Solution: Implement Letter Guessing Game

secret_word = "football"

guessed_word = '_' * secret_word.length
attempt = 0

print "My secret word: "
while secret_word != guessed_word
    puts guessed_word.chars.join(" ")
    attempt += 1 
    print "Guess a character that appears in the secret word: "
    guess = gets.chomp
    print "Try #{attempt}: "
    secret_word.length.times do |index|
        if secret_word[index] == guess
            guessed_word[index] = secret_word[index]
        end
    end
end
puts guessed_word.chars.join(" ")
puts "Correct!", "You got it in #{attempt} tries"
