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…
A Graph is a nonlinear data structure used to represent connections between different things. Unlike trees, a graph does not have a root node, and it does not follow a strict parent-child structure. A graph is made up of: Simple Real-Life Example of Graph All of these form a network, and networks are best represented…
