My Leetcode Solution in C++

How to use

We use just to make it easy to install, run and test:

1. just setup: Setup all enviroment with uv
2. just conan-install: Install all dependencies by conan
3. just configure: Do configure for CMake
4. just build: Build the whole project
5. just run: Run the main problem get program. With no arguments it stays interactive; with arguments it runs the command directly.
6. just test: Run tests for whole projects
7. just cppcheck: Run cppcheck
8. just coverage: Configure with coverage enabled, build, test, and write reports under coverage/
9. just clean-all: Remove all generated files
10. just ci: Build, run tests, and run cppcheck in order; stop on failure

Pass a problem id to work on one solution without building or running the others:

just build 57
just test 57
just coverage 57
just cppcheck 57
just ci 57

Both 57 and 0057 select src/solution/s0057_*.cpp. Run just configure once after updating the build configuration. Single-solution tests build their own executable before running. Single-solution cppcheck uses the compilation database with a file filter to analyze only the selected solution. Single-solution coverage reports are written to coverage/0057/ without processing other solutions' coverage data. Enabling coverage changes compiler flags, so a later full build may rebuild other targets. Omit the id to keep the existing whole-project behavior.

Run just configure before the first just ci. Both just ci and just cppcheck return a nonzero exit code when cppcheck reports unsuppressed findings. These local checks do not replace the remote CI's platform matrix or other checks.

Commit Message Convention

Commit messages must follow Conventional Commits with the following rules enforced by commitlint (see .commitlintrc.js):

Format

<type>(<scope>): <subject>

Allowed types (type-enum)

• solve - add a solution for a problem
• retry - retry a previously failed submission (see scope rules below)
• skip - skip a problem
• refactor, docs, test, revert, perf, build, chore, fix, ci, style - conventional types

Scope rules (scope-format)

Problem-related types (solve, retry, skip) require a 4-digit problem id as scope (e.g. solve(0042)).

In addition, the retry type must also append the failure result code, separated by a comma:

• WA - Wrong Answer
• TLE - Time Limit Exceeded
• OLE - Output Limit Exceeded
• MLE - Memory Limit Exceeded
• RE - Runtime Error
• PE - Presentation Error
• CE - Compile Error
• CREDIT

Example: retry(0001,WA)

Other types have no special scope validation.

Other rules

• Header subject is limited to 50 characters (warning)
• Body lines are limited to 72 characters (warning)
• Subject case is not enforced (both Do it and do it are accepted)

Usage

• Remove all the solution .cpp
• Clean all files in src/solution
• Start your leetcode journey by typing just run and then input the question id
• Fetch a problem directly with just run {question_id}
• To solve a problem (we should start the problem first), use just run solve {question_id} or enter solve {question_id} after just run
• To passby cloudflare, please cp .env.smaple .env, and set LEETCODE_COOKIE with your cookie (could be find in Firefox or Chrome console)
