LeetCode C Solutions

This repository is a personal archive of LeetCode solutions written in C.

The goal is to keep solved problems in a clean, repeatable format: each problem has a LeetCode-style short explanation, examples, constraints, the C starter signature, approach notes, and the submitted C solution.

• Full solved-problems table: docs/SOLVED_PROBLEMS.md
• Problem folders: problems/

Structure

problems/
  0001-two-sum/
    README.md
    solution.c
docs/
  SOLVED_PROBLEMS.md
ROADMAP.md
README.md

Each problem folder uses the original LeetCode number in the folder name and the page title, for example #0001 - Two Sum.

Problem Page Format

Each problem README.md should contain:

• LeetCode Style Info: status, difficulty, topics, hint, solved date, source.
• Problem Statement: short TR/EN version of what the question asks.
• Starter Code (C): LeetCode-style C function signature.
• Parameters / Return: what each input and output means.
• Examples: input/output samples with short explanations.
• Constraints: key limits from the problem.
• Approach: the core idea behind the solution.

Official LeetCode statements are not copied verbatim; pages are written in short original wording while staying close enough for revision.

Add New Solved Problem

1. Create a folder under problems/ with the LeetCode number and slug.
2. Add a short README.md with TR/EN summary, date, topics, examples, and idea.
3. Add solution.c with the LeetCode-style function and short comments.
4. Add the problem to docs/SOLVED_PROBLEMS.md.
5. Update ROADMAP.md if the problem belongs to the planned roadmap.
