🧠 Data Structures & Algorithms

Algorithmic problem solving is central to my development routine. I consistently practice and implement core data structures and algorithmic paradigms in modern C++:

📌 Core Data Structures

  • Arrays & Strings: Two Pointers, Sliding Window, Prefix Sums
  • Linked Lists: Singly, Doubly, Fast & Slow Pointers
  • Stacks & Queues: Monotonic Stack, Deque, Implementation
  • Trees & Binary Trees: Traversals, BST Operations, Tree Heights
  • Graphs: BFS, DFS, Adjacency Representations

⚡ Algorithmic Techniques

  • Dynamic Programming: 1D DP, 2D Grid DP, Subsequence Problems
  • Binary Search: Search Spaces, Lower/Upper Bounds
  • Recursion & Backtracking: Combinations, Permutations, Subsets
  • Greedy Algorithms: Interval Scheduling, Optimization
  • Sorting & Searching: Divide & Conquer, Custom Comparators

💻 Practice Repository: Maintained hands-on implementations and solutions in vikash2006-dot/DSA_Assigment.

⚔️ Competitive Programming

Focused on writing clean, optimal, and edge-case-resilient solutions under time and memory constraints:

  • 🎯 Language of Choice: C++ with standard template library (std::vector, std::unordered_map, std::priority_queue).
  • ⏱️ Focus: Asymptotic time complexity analysis, cache locality, and structured modular code.
  • 🔗 Profiles & Problem Sets:

💡 Programming Philosophy
"First, solve the problem. Then, write the code."
