it's a slow set...) But if for some reason you forgot to do any of them, then the problem occurs. When we use a priority_queue for Dijkstra algorithm, we usually put the same node into the queue whenever the distance is updated. This means that in the worst case we can have O(...

刷题刷题,刷的是题,培养的是思维,本仓库的目的就是传递这种算法思维。我要是只写一个包含 LeetCode 题目代码的仓库,有个锤子用?没有思路解释,没有思维框架,顶多写个时间复杂度,那玩意一眼就能看出来。 只想要答案的话很容易,题目评论区五花八门的答案,动不动就秀 python 一行代码解决,有那么多人点赞。问题...
