📊 Graphs in DSA | Types, Applications, BFS & DFS 🔥| Java Implementation🚀 + LeetCode 200

Hey everyone 👋😃 I’m Saki — in this video you’ll master Graphs in DSA 📊🧠 with crisp theory 📚✨, step-by-step Java implementations 💻☕ (BFS 🔄 & DFS 🌐), plus a full LeetCode 200 solution 🏝️✅ — code along 💡 and crush your interviews 🚀🔥🎯

What you’ll learn (high-value outcomes) ✅
• Graph basics: nodes, edges, representations (adjacency list vs adjacency matrix)
• Types of graphs: directed, undirected, weighted, unweighted, cyclic, acyclic
• Real-world applications: routing, social networks, recommendations, fraud detection 🌍
• BFS (Breadth-First Search) — concept, complexity, Java implementation (queue-based) 🔄
• DFS (Depth-First Search) — recursion/stack, complexity, Java implementation 🔁
• LeetCode 200 (Number of Islands) — problem breakdown, approach, code, and edge-case handling 🏝️
• Interview-ready tips: how to explain your approach, optimize, and avoid common pitfalls 🎤
