Consider a chessboard with a single Rook. A Rook can move any number of square sideways/forward, but not diagonally.
What is the minimum number of moves the Rook needs to make, in order to pass over all the squares on the chessboard and return to the original position?

• answer 18...start frm any corner move in spiral fashion
  4 such square moves * 4 moves each = 16 +2 moves to come back to original position
  total = 18
