Given a graph, we can use the O(V+E) DFS (Depth-First Search) or BFS (Breadth-First Search) algorithm to traverse the graph and explore the features/properties of the graph. Given a Binary tree consisting of N nodes with values in the range [1, N], the task is to find the distance from the root… Read More. All Articles on Binary Search Tree You can create a new DS topic and discuss it with other geeks using our portal PRACTICE. Inorder Tree Traversal without recursion and without stack! 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). The task is to do Breadth First Traversal of this graph starting from 0. Expected Time Complexity: O(V + E) Suffix Array and Suffix Tree: Recent Articles on Advanced Data Structures.
