The video tutorial explains the concept of heaps, a type of binary tree with specific properties. It covers the operations performed on heaps, such as insertion, accessing, and removing elements. The tutorial contrasts the traditional tree representation of heaps, which uses pointers, with a more efficient array representation that uses mathematical relationships to determine parent-child connections. The video also demonstrates how to map a heap from a tree structure to an array, highlighting the efficiency and performance benefits of this approach.
