# 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 | |
