How it works
A peg solitaire simulator. Inputs are:
- The x co-ordinate of the peg to move
- The y co-ordinate of the peg to move
- The direction to move the peg in
- LEFT is 0b00
- RIGHT is 0b01
- UP is 0b10
- DOWN is 0b11
Outputs are:
- The number of pegs remaining
- A bit to indicate game over, i.e. no remaining legal moves.
If the x/y coordinates are outside of the usable grid, or does not contain a peg, the state stays the same.
Starting state of the board:
0 1 2 3 4 5 6
0 x x x
1 x x x
2 x x x x x x x
3 x x x 0 x x x
4 x x x x x x x
5 x x x
6 x x x
