What You'll Learn
- Master Binary Tree Traversals: Execute and implement recursive and iterative Depth-First Search (DFS) and Breadth-First Search (BFS) traversals in Python.
- Solve BST Operations: Construct, validate, insert, delete, and search nodes efficiently in Binary Search Trees (BST).
- Identify Structural Properties: Calculate essential tree metrics including maximum depth, diameter, symmetry, and balanced status.
- Implement Graph Representations: Convert problem constraints into optimized Adjacency Lists and Adjacency Matrices using native Python data structures.
- Detect Graph Cycles: Build cycle detection algorithms for both directed and undirected graphs using DFS, BFS, and color-marking strategies.
- Apply Shortest Path Algorithms: Implement Dijkstra’s algorithm and BFS to find optimal routes and shortest paths in weighted and unweighted graphs.
- Master Topological Sorting: Solve dependency-ordering and course-schedule problems using Kahn’s Algorithm (Indegree Array) and DFS.
- Utilize Disjoint Set Union (DSU): Implement Union-Find with path compression and rank optimization to tackle dynamic connectivity problems.
- Recognize LeetCode Patterns: Instantly identify core algorithmic patterns such as Flood Fill, Lowest Common Ancestor (LCA), and Topological Sort in unseen inter
- Analyze Complexity confidently: Evaluate time and space complexity ($O(V + E)$ for graphs and $O(N)$ for trees) for both recursive call stacks and iterative sol
- Optimize Recursive Solutions: Avoid common pitfalls like recursion depth limit errors and unnecessary re-computations by managing recursive state effectively in
- Write Clean, Interview-Ready Python: Implement idiomatic Python features (such as collections.deque, heapq, and nested functions) to write production-quality co
