MaxHeap and MinHeap in the Go standard library

I hope this helps you . It supports both by letting you implement a Less function comparing two elements. If your Less(i,j) returns true if i code :

MinHeap and MaxHeap implementation in Java

To fix the issue you can do I think you have it backwards: a heap is a way of implementing a priority queue. As for the min / max part, simply write the appropriate Comparator classes.

Moving minheap.top to maxheap.top where maxheap.top <= minheap.top

seems to work fine What you really need is an efficient way to insert into a priority queue when you know that the element being inserted is smaller/bigger than the min/max, depending on whether this is a min-heap or a max-heap. For the traditional "heap" data structure, this takes O(log n) time.
But if you are willing to use a different representation for your priority queues than the traditional "heap" data structure, then such an insert can trivially be made to run in O(1) time. Many different kinds of priority queues can do this, such as leftist heaps, skew heaps, or pairing heaps.

Is heapsort more efficient when used on a minheap or maxheap?

wish of those help The following is my take on it, and I could be incorrect, but here goes. In theory, they're equally efficient.
Heap Sort works basically by placing all elements into a (min)heap and then, now that they're in heap order, repeatedly removing the minimum element until the heap is empty, giving us the data in increasing order. It's O(nlogn) since we do linear passes through the data, and the heap supports a log n insertion/removal for the work that we do for each element in the data.

MinHeap/MaxHeap implementation in Python

I wish this help you These classes are based on Python's heapq structure, which is built on a standard Python list. The smallest item in the minheap and the largest item in the maxheap is at index zero. So just return
code :
self.heap[0]

Is there a maxheap in the C++ standard library?

hope this fix your issue Regarding std::priority_queue:
