C++ DSA Starter 🚀

This repo is a minimal C++ crash course focused on Data Structures & Algorithms.
It covers only the 20% of C++ that gives 80% benefit for solving problems on LeetCode & in contests.

Structure

• template.cpp → Base template with fast I/O (use this as your starting point).
• 01_basics/ → Core syntax lessons (I/O, auto, references, memory, OOP).
• 02_stl/ → STL essentials (vector, string).
• practice_problems/ → Concept-based small problems for practice.
• leetcode_homework/ → LeetCode problem skeletons (copy-paste ready).

How to use

1. Open this repo in VS Code:

   code .

2. Compile any file using:

   g++ -std=c++17 filename.cpp -o run
   ./run

3. Solve practice problems → then attempt the linked LeetCode homework.

Learning plan

• Week 1: Basics (Lessons 1–5)
• Week 2: STL containers (Lessons 6–10)
• Week 3: Helpers (stack, queue, priority_queue, lambdas)
• Week 4: Problem-solving patterns (two pointers, binary search, trees, graphs)

End goal → 30–50 solved LeetCode problems + clean C++ DSA foundation 🎯
