Inleiding
Data Structures and Algorithms (DSA) Overview
- Definition: DSA comprises Data Structures (managing data storage/access) and Algorithms (processing data).
- Importance:
- Foundational for software including GPS, Search Engines, AI, Gaming, and Databases.
- Core focus for technical interviews at top-tier companies like Google, Meta, Amazon, and Microsoft.
- Enhances problem-solving skills and programming proficiency.
- Learning Strategy: Beginners are advised to skip "Hard" problems during the first iteration of study.
- Core Curriculum Topics:
- Fundamentals: Programming basics, Complexity Analysis (Big-O, Time/Space complexity), Maths, and Recursion.
- Data Structures: Arrays, Strings, Matrices, Linked Lists, Stacks, Queues, Deques, Binary Trees, Binary Search Trees (BST), Heaps, and Graphs.
- Algorithmic Patterns:
- Searching: Linear, Binary, and Search on Answer/Two.
- Sorting: Quick Sort, Merge Sort, Cycle Sort, and variants.
- Bit Manipulation: Bitwise operations and subsets.
- Hashing: Probing, chaining, and frequency counting.
- Two-Pointer & Sliding Window: Fixed/variable length windows and optimization techniques.
- Prefix Sum: Range queries and difference arrays.
- Backtracking: Permutations, N-Queens, and Sudoku solvers.
- Graph Algorithms: BFS/DFS, Topological Sorting, and cycle detection.
