-/**
- * Design a Snake game that is played on a device with screen size = width x height. Play the game online if you are not familiar with the game.
- * <p>
- * The snake is initially positioned at the top left corner (0,0) with length = 1 unit.
- * <p>
- * You are given a list of food's positions in row-column order. When a snake eats the food, its length and the game's score both increase by 1.
- * <p>
- * Each food appears one by one on the screen. For example, the second food will not appear until the first food was eaten by the snake.
- * <p>
- * When a food does appear on the screen, it is guaranteed that it will not appear on a block occupied by the snake.
- * <p>
- * Example:
- * Given width = 3, height = 2, and food = [[1,2],[0,1]].
- * <p>
- * Snake snake = new Snake(width, height, food);
- * <p>
- * Initially the snake appears at position (0,0) and the food at (1,2).
