MyLeetcodeSolutions

Leetcode Profile :- https://leetcode.com/u/harsh9265/

A curated collection of my solutions to LeetCode problems — with clean code, clear explanations, and learning notes.

Goal: Build strong problem-solving skills by organizing solutions by topic, tracking progress, and reflecting on patterns and trade-offs.

🧩 How I Write Each Solution

Every solution includes:

• Approach & intuition (why this works, key idea, and patterns used)
• Time & space complexity
• Edge cases
• Code with comments
• Optional: alt approaches (e.g., brute force vs optimized)

I often use py on Windows (same as my local workflow).

🧠 Topics Covered

• Arrays & Strings
• Hash Map / Hash Set
• Two Pointers
• Sliding Window
• Stack / Queue
• Binary Search
• Linked List

🧭 How I Practice (and what I’m focusing on)

• Start with brute force, then optimize.
• Identify pattern early: sliding window, two pointers, prefix sums, etc.
• Write down complexity before coding.
• Add 2–3 sanity tests per solution.
• Reflect in the per-problem README: “What tripped me up?”

Current focus: sliding window, two pointers, hash map (my common interview set).

---

🔁 Roadmap

• Add C++/Java versions for popular problems
• Add benchmarking script for runtime comparisons
• Add explanations with visuals where helpful
• Automate problem scaffolding with a CLI (create folder + template)
• Add CI (run tests on push via GitHub Actions)
