问题背景 实现Priority Queue的不同思路(着重介绍后两种) 代码分享 obj 是顶端节点的指针 在代码实现中 我没有将顶端节点变为虚节点 而跟binary tree一样 顶端节点就是最优先的元素 这在实际实现中可能造成一些冗余代码 总结与思考——debug分享至 投诉或建议...

当你在处理数据结构，如pQueue（优先队列）时，可能会遇到这样的情况：</当你试图从pQueue中获取队首元素的值，例如使用pQueue->head，通常这个操作会返回一个指向队首元素的指针，而不是一个布尔值。然而，如果你得到的是一个bool值，那可能意味着在某个点上，队列为空（pQueue->head == NULL）...
PQueue.prototype.isEmpty =function() { returnthis._records.length == 0; }; //清空队列 PQueue.prototype.clear =function() { this._records.length = 0; }; 我觉得,相对于其他排序算法而言,用堆实现优先级队列,入队时间波动较小,比较平稳。
Currently, developers must rely on third-party libraries likep-queueto handle such scenarios. This reliance introduces additional dependencies, increases project size, and may impact performance. A native solution likeBun.PQueuewould streamline development, enhance performance, and reduce dependency manageme...
