In my past few contests, including the most recent one, I have noticed that I keep getting stuck on easy problems which prevents me from being able to devote more time to solving harder ones. For instance, in th

1.若当前k>size(堆大小),弹出堆顶至size=k。 2.若堆中可以直接加入当前问题(k<size和满足时限),则直接加入。 3.否则考虑是否可以替换堆顶,可以则替换。 每次统计答案,找到最大值。 观察三个操作,容易发现当出现k>size的情况后,答案不可能再变大,也就是答案是一个凸函数,顶点出现在k>size时。 所以只需要...
