Concept explainers

Heap Sort

A Heap is a type of data structure that is built on trees. It's a binary tree that's virtually complete. Except for the very bottom level, all levels of the tree must be filled in a heap. The last (bottom) level should be filled from left to right. The heap data structure is used for the efficient implementation of priority queues.Heap can be of two types:

Question

Pls. answer the 2 questions. write a short explanation each.

If we are to convert this array [23, 12, 15, 3, 42, 8, 11] to a heap, then the last non-leaf element is:
42
15
3
12

The problem with selection sort lies with:
Swapping adjacent elements
Scanning the remaining unsorted elements
Selecting the minimum among the list
O Selecting the maximum among the list
