复现演示：
只有0-5号鱼竿时，输入不存在的6号竿，会引起报错。

推测是max值边界有问题,有空再修

POLE.GO:

		max := len(articles)

.....

if first == second || first == third || second == third {
						ctx.SendChain(message.At(ctx.Event.UserID), message.Text("[0]请输入正确的序号\n", list))
						continue
					}
					if first > max || second > max || third > max {
						ctx.SendChain(message.At(ctx.Event.UserID), message.Text("[", max, "]请输入正确的序号\n", list))
						continue
					}
