Things to improve: 1. You may only guess the word once, any input of more than 1 character will be treated as an attempt to guess the word. 2. There is no input validation, invalid input is treated as a guess 3. This doesn't track guesses you've already made

	#!/usr/bin/env ruby

	word_bank = ["this", "is", "the", "word", "bank"]
	word = word_bank.sample
	remaining_guesses = 10
	guess = ""
	display = "_" * word.length

	until guess == word \|\| remaining_guesses == 0 \|\| display == word
	puts "Word : #{display}"
