Givenheadwhich is a reference node to a singly-linked list. The value of each node in the linked list is either 0 or 1. The linked list holds the binary representation of a number. Return thedecimal valueof the number in the linked list. Example 1: Input: head = [1,0,1] Output: ...
Insertion: we insert the node into the leaf, and max(min)heapify the heap to restore the ordering, the worst case run time is O(nlogn). Deletion: swap the node that was intended to be deleted (usually the root for max or min element) with the leaf, delete the leaf, and max(min)...
