If multiple plans exist, choose the one that spends as long as possible at lake 1, even if no fish are expected to be caught in some intervals. If there is still a tie, choose the one that spends as long as possible at lake 2, and so on.
那啥，这个是原题上的话。我觉得大大概意思就是说，如果有多条湖符合要求，那么那个人会选择最靠前的湖，即序号最小的湖……所以，一开始用贪心算法的时候是正常的，当两个都为零的时候，那个人会优先选择序号小的那个湖来消磨时间，因此剩下的时候都耗在了第一条湖上。
