# The computer asks the user for two numbers in a range
# The computer then asks the user to think of a number within that range

# The computer then provides a series of guesses and asks the user if
# guess is correct

# If the guess is too high, the user types "h"
# If the guess is too low, the user types "l"
# If the guess is correct, the user types "y"

# If the guess was correct,
# the program then prints "Yay!" and quits
