Toroidal Snake
(Published on 25. January 2018, 19:51 by zhergan)
Find a snake of length 47. Head and the tail of the snake are already predetermined. The snake goes from cell to cell vertically or horizontally, but not diagonally. The snake does not touch itself, not even diagonally. The numbers outside the grid indicate how many squares are used by the snake in that row or column. Additionally in this variant the grid is a torus, i. e. the left and right border of the grid as well as the upper and bottom border are connected.
Solution code: Row 5, followed by column 4. 'S' for snake, '-' for an empty cell.
