Solve the Ring Problem
Move all the three discs from peg 1 to peg 3, so
that the RED disc is on the bottom, BLUE disc is in the
middle, and the GREEN disc is on top. You may move only
one disc at a time, and only to another peg; you may not
place a larger disc on top of a smaller one. A disc can
only be moved between the adjacent pegs.
