BFS is useful for analyzing the nodes in a graph and constructing the shortest path of traversing through these. BFS can traverse through a graph in the smallest number of iterations. The architecture of the BFS algorithm is simple and robust. The result of the BFS algorithm holds a high level of accuracy in comparison to other algorithms.
For BFS algorithm, visiting a node’s siblings before its children, while in DFS algorithm, visiting a node’s children before its siblings ... In these problems, one unit of work is shooting one balloon. • Scenario 1: For every 2 balloons you are able to shoot, one new balloon is inserted in the
BFS is different from DFS in a way that closest vertices are visited before others. We mainly traverse vertices level by level. Popular graph algorithms like Dijkstra’s shortest path, Kahn’s Algorithm, and Prim’s algorithm are based on BFS.; BFS itself can be used to detect cycle in a directed and undirected graph, find shortest path in an unweighted graph and many more problems.

Breadth First Search (BFS) There are many ways to traverse graphs. BFS is the most commonly used approach. BFS is a traversing algorithm where you should start traversing from a selected node (source or starting node) and traverse the graph layerwise thus exploring the neighbour nodes (nodes which are directly connected to source node).
Breadth First Search (BFS) is a graph traversal algorithm that explores all the vertices of a graph at a given depth level before moving on to the next depth level.Starting from a given source vertex, BFS explores all its adjacent vertices first, then the adjacent vertices of those vertices and so on, until all vertices reachable from the source vertex are visited.
Because the problem statement highlights the goal as counting the number of cities at each distance from the capital, intuitively, BFS comes to mind as we would stay on that city’s level and ...
