Practice shortest-path thinking and use a guided week-by-week roadmap for focused interview preparation.
Visual practice for graph traversal, sorting, complexity understanding, and interview prep.
Use shortest path checks and a weekly plan to prepare with structure.
Unweighted Shortest Path
Start: A | Target: G
Path: A -> B -> D -> F -> G
4-Week Interview Sprint
The Advanced DSA Lab goes beyond isolated problems — it includes pathfinding visualizations (Dijkstra, A*) and a structured 4-week interview sprint plan. The lab is designed for candidates in the final weeks before technical interviews.
Visualize sorting algorithms in Sorting Visualizer or explore graph traversals in Graph Visualizer.
Graph algorithms (Dijkstra, A*, BFS/DFS), dynamic programming (knapsack, LCS, coin change), and advanced data structures like segment trees and tries.
Dijkstra explores all directions equally to find shortest paths. A* adds a heuristic estimate to the goal, making it faster for single-target pathfinding.
Dedicate 2–4 weeks per topic area. Week 1: learn theory + easy problems. Week 2: medium problems + timed practice. Week 3–4: hard problems + mock interviews.
