Consider a graph with five nodes labeled A, B, C, D, and E. Let's say we have the following edges with their weights:A to B with weight 3A to C with weight 1B to C with weight 3B to D with weight 1C to E with weight 4D to E with weight 2a. Find the shortest path from A to E using Dijkstra's algorithm (Would anything change if B to C weight was changed from 3 to 4? To 1? What about 5?)

Dijkstra's algorithm is a graph search algorithm that solves the shortest-path problem for a graph with non-negative edge path costs, producing a shortest path tree.It works by visiting vertices in the graph starting with the object's path source vertex, then it selects its nearest neighbor and checks if the path to the vertex can be shortened by going through it. The process continues until all the vertices have been visited, effectively finding the shortest path to all vertices in the graph from the source vertex.Thus, shortest path from A to E is A -> C -> E with cost 5.
