📖About This Course
Master Data Structures & Algorithms through 600 carefully crafted practice questions spanning everything from array fundamentals to advanced graph theory and complexity analysis.This course is organized into six comprehensive practice tests, each with 100 multiple-choice questions. Every question includes a detailed explanation for all four answer options, not just the correct one, so you understand the reasoning behind each concept rather than simply memorizing answers.Test 1: Arrays, Strings & Two Pointers/Sliding Window — Two-pointer techniques, sliding windows, binary search, hash maps, and classic algorithms like Kadane's and the Dutch National Flag problem.Test 2: Linked Lists, Stacks & Queues — Fast-and-slow pointers, cycle detection, the LRU cache, monotonic stacks, and stack/queue implementation tradeoffs.Test 3: Trees, Tries & Graphs — Binary search trees, tree traversal, tries, BFS/DFS, topological sort, union-find, and shortest-path algorithms.Test 4: Sorting, Searching, Recursion & Backtracking — Merge sort, quicksort, heap sort, N-Queens, Sudoku-solving, and advanced binary search variants.Test 5: Dynamic Programming — Knapsack, longest common subsequence, interval DP, state-machine DP, and recognizing when greedy shortcuts genuinely apply.Test 6: Advanced Graphs, Greedy Algorithms & Complexity Analysis — Bellman-Ford, Floyd-Warshall, exchange-argument proofs, NP-completeness, and approximation algorithms.Whether you're preparing for technical interviews, filling gaps from self-taught learning, or sharpening algorithmic intuition as a working engineer, this course gives you a structured, thorough way to test and deepen your understanding.
