Tarjan's Algorithm for Finding the Lowest Common Ancestor (LCA)

1. Introduction When dealing with tree structures, it is common to encounter the need to find the Lowest Common Ancestor (LCA) of two nodes. The LCA is defined as the furthest node from the root among all common ancestors of the two nodes in the tree (i.e., the node with the maximum depth). For example, … Read more

C++ Search Algorithms: Depth-First Search and Breadth-First Search

C++ Search Algorithms: Depth-First Search and Breadth-First Search In computer science, search algorithms are essential tools for solving problems related to graphs, trees, and other structures. The two fundamental search strategies are Depth-First Search (DFS) and Breadth-First Search (BFS). This article will provide a detailed introduction to these two algorithms and demonstrate them using C++ … Read more
