PROBLEM

Use PHP or Perl/CGI to implement the following game.

Your program starts by choosing a random number between 1 and 100. It then offers the user 10 chances to guess the number. Each time the user enters a number the program replies in one of three ways:

if the user enters a number that's bigger than the secret number the program reports that and also counts the attempt. If the number of attempts becomes bigger than 10 the user has lost, is notified, and number is shown.
if the user enters a number that's smaller than the secret number the program reports that and also counts the attempt. If the number of attempts becomes bigger than 10 the user has lost, is notified, and number is shown.
if the user has guessed the number then the user is notified, congratulated.

The interface should be an HTML form with one text field and one submit button.

Comments:

This is almost identical to the calculator program of homework 2 and 3
Instead of a running balance we keep track of a running number of attempts
We also carry around a secret number that doesn't change
Each time user submits a number the number submitted is checked against the secret number
Assume an honest user that never tries to cheat on you in any way

GRADUATE STANDING:

Add a Reset button, that restarts the game.
