2. Intelligent snake

Although intelligent, it may not be as intelligent as you think.
The basic idea is to followTop, right, bottom, leftThe sequential search direction allows you to move in this direction closer to food. obstacles encountered during the forward process will be automatically bypassed, but the situation that the snake head is surrounded by a snake cannot be avoided.
