The shortest path problem requires us to find out the shortest possible route between nodes in a graph. It has important applications for mapping and route planning, when plotting the most efficient way to get from point A to point B.
Dijkstra's algorithm is a very popular method of solving this problem. This algorithm is used to find the shortest distance from a source to all other nodes or vertices in a graph. Here we explain how we can use the greedy approach to solve this problem.
Dijkstra's algorithm works for weighted directed and undirected graphs. The algorithm produces the output of a list of the shortest path from a given source node A in a weighted graph. The algorithm works as follows:
- Initially, mark ...
