LeetCode via NeetCode

Benchmarked C# submissions for LeetCode problems with naïve F# solutions on my functional programming journey.

After stumbling across the excellent NeetCode website I'm now following the author's guidance and supporting his work by becoming a lifetime member. 🙇‍

Build and test

Install the .NET 10 SDK, version 10.0.400 or later. global.json rolls forward to the newest feature band you have.

> dotnet --list-sdks
10.0.402 [/usr/share/dotnet/sdk]

> git --version
git version 2.56.0

> git clone https://github.com/si618/leetcode.git
Cloning into 'leetcode'...

> cd leetcode
> dotnet build
> dotnet test

Tests run on xUnit v3 with Microsoft.Testing.Platform, and sit beside the solution they test.

# Run a single test
> dotnet test --project LeetCode.CSharp --filter-method "*TwoSumTest"

# Write TRX results and Cobertura coverage to artifacts/test-results, as CI does
> dotnet test --report-xunit-trx --results-directory artifacts/test-results --coverage --coverage-output-format cobertura

Build output goes to artifacts/, not to bin/ and obj/ in each project.

Console application

An interactive console application can run benchmarks and show problem information.

> cd ./LeetCode
> dotnet run
USAGE:
    LeetCode.exe [OPTIONS] <COMMAND>

EXAMPLES:
    LeetCode.exe benchmark LRUCache --csharp
    LeetCode.exe info MergeTwoLists

OPTIONS:
    -h, --help       Prints help information
    -v, --version    Prints version information

COMMANDS:
    app          Run interactive console application
    benchmark    Run benchmarks against leetcode problems
    info         Show information about a problem
    list         List information about problems
    workflow     Run benchmarks for GitHub workflow

> dotnet run app
