A Java program that uses DFS to generate all the possible patterns on a traditional 3x3 Android lock screen

The program generates all the possible 389,112 patterns and creates 2 files:

• sequential.txt that contains the patterns arranged sequentially
• shuffled.txt that contains the patterns arranged randomly

For reference, the numbers in the output are mapped to the points as:

0 1 2 3 4 5 6 7 8
