73 1.0.0

73 CLI

The interactive command-line companion to practice, test, and master the 73 most useful LeetCode problems in C# with zero boilerplate and immediate feedback.

Features

• Zero Boilerplate: Write only public class Solution { ... } (the exact LeetCode snippet). No .csproj, no Program.cs, no Main().
• In-Memory Roslyn Execution (< 100 ms): Code is compiled dynamically in memory using Microsoft.CodeAnalysis.CSharp for instant feedback.
• Rich Terminal UI: Clear panels, progress indicators, and comparative diff tables powered by Spectre.Console.
• Smart Problem Resolver: Automatically detects which problem you are testing by directory location, fuzzy filename (two.cs), or AST method signature inspection (TwoSum(...)).
• 100% Self-Contained: All 76 problem test suites, templates, and problem notes are embedded. Works in any directory.

Installation

Install globally as a .NET Tool:

dotnet tool install -g 73

To update to the latest version:

dotnet tool update -g 73

Quickstart

1. Generate a boilerplate solution

73 new two-sum

Creates Two-Sum.cs with the exact LeetCode method signature:

using System;
using System.Collections.Generic;

// Problem: #0001 - Two Sum [Easy]
public class Solution
{
    public int[] TwoSum(int[] nums, int target)
    {
        throw new NotImplementedException();
    }
}

2. Solve and test immediately

Run 73 pointing to your file:

73 Two-Sum.cs

Or run tests directly by problem name:

73 test Two-Sum
