Min Heap: An Introduction
Explore the fundamentals of Min Heaps, including how to build them from arrays and maintain heap properties through insertion and deletion. Understand step-by-step procedures and visual cues to ensure the Min Heap property is preserved throughout operations, preparing you for coding interviews and Java implementations.
We'll cover the following...
Building a Min-Heap
A Min Heap follows the Min Heap property, which means the key at the parent node is always smaller than keys at both children nodes.
Heaps can be implemented using arrays. Initially, elements are placed in nodes in the same order as they appear in the array. Then a function is called over the whole Heap in a bottom-up manner, which “Min Heapifies” this Heap so that the Heap property is satisfied on all nodes.
When we say bottom-up, we mean the function starts from the ...
