Which algorithm would you use to find the shortest path in an unweighted graph?

Step 1: Understand what an unweighted graph is. An unweighted graph is a graph where all edges have the same weight or cost, typically considered as 1.
Step 2: Learn about the Breadth-First Search (BFS) algorithm. BFS explores all neighbors of a node before moving on to the next level of nodes.
Step 3: Start BFS from the source node (the starting point of your path).
Step 4: Use a queue to keep track of nodes to explore next. Enqueue the source node first.
Step 5: While the queue is not empty, dequeue a node and check if it is the destination node (the endpoint of your path).
Step 6: If it is the destination node, you have found the shortest path. If not, enqueue all its unvisited neighbors.
Step 7: Repeat steps 5 and 6 until you find the destination node or the queue is empty.
