Subject: If you like coding puzzles...

In 3 weighings find the odd ball and whether it is lighter or heavier. There are at least 2 solutions, neither of which I remember off hand. 2) 6 balls, 2 red, 2 white, 2 blue. One of each color is Heavy, one of each is Light. Heavies all weigh the same as do Lights. In 2 weighings, label the balls. (3 is of course triv). -dg
