Data Analyst Interview Questions and Answers

A Heap is a special Tree-based Data Structure in which the tree is a complete binary tree. Generally, heaps are of two types: Max-Heap and Min-Heap. To know more about this Data Structure in-depth refer to the Tutorial on Heap Data-Structure.

Given below are the most frequently asked interview questions on Heaps:
