Questions & Step-by-Step Solutions
In which scenario would you prefer Dijkstra's algorithm over Bellman-Ford algorithm?
Step 1: Understand that both Dijkstra's and Bellman-Ford are algorithms used to find the shortest path in a graph.
Step 2: Know that Dijkstra's algorithm works best when all the weights (distances) on the edges of the graph are non-negative (zero or positive).
Step 3: Recognize that Bellman-Ford can handle graphs with negative weights, but it is slower than Dijkstra's algorithm when there are no negative weights.
Step 4: Conclude that if you have a graph with only non-negative weights, you should choose Dijkstra's algorithm because it will find the shortest path faster.
