Topological Sort is a linear ordering of vertices in a Directed Acyclic Graph (DAG) such that for every directed edge u → v, node u comes before v in the order. Key Points (Quick Revision) Topological Sort in Simple Words Topological Sort means: Real-Life Example Think about: This is dependency-based ordering, that is, Topological Sort….
Depth First Search (DFS) is a graph traversal algorithm that explores nodes as deep as possible before backtracking. It uses a stack (or recursion) to visit nodes. Key Points (Quick Revision) DFS in Very Simple Words DFS means: It works like exploring a maze. Real-Life Example Imagine: This is exactly how DFS works. Example Graph…
Breadth First Search (BFS) is a graph traversal algorithm that visits nodes level by level using a queue (FIFO). It is commonly used to find the shortest path in an unweighted graph. Key Points (Quick Revision) BFS in Very Simple Words BFS is like spreading out step by step. It works like a wave or…
