shortest distance is determined, it will not change.

Step-by-step process:

1. Initialize distances: set the source vertex distance to 0 and all others to infinity.
2. Use a priority queue to select the vertex with the smallest distance.

3. For each neighbor of the selected vertex, update its distance if a shorter path is found.

4. Repeat until all vertices are processed.

Example in C++:

This program demonstrates Dijkstra’s algorithm on a weighted graph. The output

shows the shortest distances from the source vertex to all others.
