All Articles on Array We help companies accurately assess, interview, and hire top tech talent. Breadth First Traversal (or Search) for a graph is similar to Breadth First Traversal of a tree (See method 2 of this post).The only catch here is, unlike trees, graphs may contain cycles, so we may come to the same node again. Actually when running BFS (to find the shortest path) you should initialize your nodes with a "distance" parameter with a very large number and instead using the visited DS, you update it to the parent's distance + 1 (only if it's still with the initialized value).
