Leetcode Boilerplate Generator

Ever had to debug Leetcode problems? Debugging a Leetcode problem on their website is behind a paywall. And running & debugging a Leetcode problem locally requires you to write the driver code that will call the problem function with example inputs & outputs, lc-boilerplate-generator can do just that for you. This can generate compilable driver code in C++ and Rust with example inputs and assertions against their expected outputs. If the problem inputs and/or outputs are primitive data types or 1-D or 2-D arrays, then this can generate driver code for it.

Not Supported:

• Problems based on dynamic data structures like Linked List, Tree.
• Problems based on writing a class for a custom data structure.

Generated boilerplate code for Rust

Generated boilerplate code for C++

How to Use

• ./lc-boilerplate-generator <leetcode-problem-url> <language> (supported languages: cpp, rust)

Or

• ./lc-boilerplate-generator and it will ask for both these input.

Setup

• Install Rust from https://rustup.rs/
• Run with cargo run or Build binary with cargo build --release

TODO

• Support Java and Python
• Handle problems where return type is void & the problem checks the updated version of the input, e.g. this LC Problem
