Project Notes

This program generates a random passcode using an algorithm (described below). You can test if a passcode is valid by using the number input. To use the number input, click on a number box, then press the up or down keys until it says the number you want. After you have the number input ready with the passcode you want, click the Test Passcode button to test if the passcode is valid. Here is the algorithm. We will refer to the third, fourth, and fifth numbers as a, b, and c, and the first two numbers as x (they are really read as one single number). x = (a*b) + c Basically, the testing algorithm finds out x, a, b, and c from the passcode, and tests if the algorithm is true. If it is, it's valid; if not, it's invalid.
