As an example, consider a stack of dishes stacked on top of each other. The plate we put last is on top, and because we take the plate at the top, we may claim that the plate we put last comes out first.Basic Operations on…

There are a few instances when duplicate nodes can occur in the heap when using Dijkstra’s algorithm:Case 1: When multiple edges have the same weight between two vertices, a duplicate node can be added to the heap when updating the distance from the starting vertex to the neighboring vertex. For example, consider the following graph:       A     /  \  B    C  /     /  \D   E   FEdge weights between these vertices are:AB = 2, AC = 3, BD = 1, CE = 2, CF = 2, DE = 2If we start at vertex A and use Dijkstra’s algorithm to find…
