Step-by-Step Analysis
To begin, let's restate the question to ground our analysis: How many children can a node in a binary heap have?
Option 1: 'At most 2' — The defining feature of a binary heap is that each node has at most two children (left and right). This matches the 'binary' ......Login to view full explanationLog in for full answers

Heap Algo 4 You are using the HeapPriorityQueue class implemented with a binary min-heap, which is stored as an array (Python list) in level-order. The heap currently stores the following key-value pairs: [(2, 'A'), (4, 'B'), (6, 'C'), (8, 'D'), (5, 'E')] After calling remove_min() once, what will be the contents of the heap (in array/list format)? (Assume that the heap properties are restored correctly after the operation.) Pseudocode for remove_min() remove_min(): swap the root with the last element remove the last element (which is the min) call _downheap(0) Pseudocode for _downheap(j) _downheap(j): if left child exists: small_child = left if right child exists and right < left: small_child = right if small_child < j: swap(j, small_child) _downheap(small_child) In this implementation, for an element at index j: Left child is at index 2j + 1 Right child is at index 2j + 2 Parent is at index (j - 1) // 2
