Data Structures for Coding Interviews in Java

Why Use Heaps?

Explore the importance of heaps in computer science by understanding their key applications such as efficient priority queues, sorting with HeapSort, and order statistics. This lesson helps you grasp how heaps improve algorithm performance and are implemented in Java, preparing you for coding interview challenges.

We'll cover the following...

Where are Heaps Used?

Just like other data structures, Heaps are also used in many computing algorithms. The major uses of Heaps are elaborated below:

  1. Order statistics: Heaps are primarily used for efficiently finding the smallest or largest element in an array.

  2. Priority Queues: Priority queues can be efficiently implemented using Binary Heap because it supports insert(), delete(), extractmax(), and decreaseKey() operations in O(logn ...
