我正在尝试使用std::priority_queue创建一个maxheap和一个minheap。只创建一个maxheap可以很好地工作,但不能同时创建两个。我似乎不能理解这个错误。我收到以下错误:无法将‘minHeap’从‘std::priority_queue,compare>’转换为‘std::priority_queue’尝试在互联网上搜索,但无济于事。下面是代码。void addNum(int...

Heap data structure is always a Complete Binary Tree, which means all levels of the tree are fully filled. In Min Heap, both the children of each of the nodes are greater than their parents. To understand the basic functionality of the Priority Queue in CPP, we will recommend you to visi...
