Programmer Puzzle: Encoding a chess board state throughout a game
...goal).
In base 10 the number 234 is equivalent to 2 x 102 + 3 x 101 + 4 x 100.
In base 16 the number 0xA50 is equivalent to 10 x 162 + 5 x 161 + 0 x 160 = 2640 (decimal).
So we can encode our position as p0 x 1363 + p1 x 1362 + ... + p63 x 130 where pi represents the contents of square i.
