Takes a currency input and amount tendered, validates input, returns amount of change due.
puts "What is the amount due?"
amount_due = gets.chomp
if (amount_due[/^[1-9]\d*(\.\d+)?$/] == false) || (amount_due.scan(/\./).length > 1)
puts "Warning: Invalid currency detected! Exiting..."

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}"

Program will suggest next train based on departure time. If a train leaves exactly at departure time it will be suggested. If suggestion is before or after train times it will tell you there's no train available.
