Python is versatile with a wide range of data structures. One such is the heap. While they are not as commonly used, they can be incredibly useful in certain scenarios. In this article, we will learn what a heap is in Python. We will also understand how to implement max heap and min...
Implementing Max Heap in Python Operations: push()– We can insert every element to the heap. We always add the item at the end of the tree. The time complexity of the operation is O(log(n)). Every time we make an insertion, we have to ensure that the heap is still in the correc...

A requirement for this data structure was that it could enable custom objects to be passed, and not only integers, so it's important to pass a tuple of the type (Object, value to add)Example:# When creating, give it a k value. m = BoundedPriorityQueue(5) print "Initial heap:", m...
To get more clear vision of how persistent heaps work (SkewHeap and PairingHeap), you can look at slides from my talk "Union-based heaps" (with analyzed data structures definitions in Python and Haskell). Note. Most functional languages use persistent data structures as basic building blocks,...

1. Divide the data elements into two sections with equal number of elements. 2. Sort the two sections separately. 3. Merge the two sorted sections into a single sorted collection. Obviously, this is a recursive idea, where a problem is divided into smaller problems. And the division will ...
