Rust blockchain developer application

[vi5hnuraj]

Applying for the Rust Blockchain Developer position via the developer path.

What's included

• answers.md — answers to all questions from questions.md
• src/lib.rs — Rust solutions for the four coding puzzles, with 11 unit tests
• src/main.rs — demo binary that prints each solution's output
• Cargo.toml — crate setup

Notes

• All puzzles are solved in Rust, the language I'm applying with.
• The rotate puzzle is done in place using the three-reversal trick — no copy of the list, exactly n swap operations.
• Pig Latin translation matches the exact example from the question and round-trips back to English.

How to run

cargo test # 11 tests passing
cargo run # prints every puzzle solution
