# Gavin Stark Psuedo Code
# 1. We remember that a is 1
# 2. We remember that b is 100
# 3. We remember that z is 0
# 4. We tell the user we are going to
#    guess a number between "a" and "b"
# 5. User chooses number
# 6. We remember our guess is (a+b) / 2
# 7. Tell the user that we are guessing the number "guess"
# 8. User chooses yes, no
# 9. If user chooses yes
#    then say we got it in z guesses
#    game is over

# Loop until guess is correct 
# 10. If user chooses no
# 11. Ask if number is higher or lower than the number "guess"
# 12. If user chooses lower
# 13.  Make b equal to guess - 1
# 14.  go back to step 6
# 15. If user chooses higher
# 16.  Make a equal to guess + 1
# 17.  go back to step 6
