python3 astar8number.py --startrow 1 2 3 8 0 5 7 4 6 --goalrow 1 6 2 8 4 3 0 5 7

Code takes input of form three elements of row 1 three elements of row 2 three elements of row 3 for both startrow and endrow

For example the above code solves using the algorithm for the follwing start and end states:

Start location

	col1	col2	col3
row1	1	2	3
row2	8		5
row3	7	4	6

Final State

	col1	col2	col3
row1	1	6	2
row2	8	4	3
row3		5	7

The code uses misplaced tiles as heuristic function and distance from start as g function.
