You might have heard about HackerRank, They rank programmers based on their coding skills, helping companies source great programmers and reduce the time to hire.
I tried to complete their 30 Days of Code Challenge. But the question is they have enable Rust only for Day 0: Hello, World. challenge . I tried to ask this from author and this is the response I got.
The blocker is just having somebody who can write the code stubs. If you're interested in writing stubs/solutions for certain challenges yourself, you can definitely do that and contact support. Then we can review/test them and enable that language for the challenge.
I'm still a newbie for Rust, so I would be very grateful if we all can work to enable Rust in HackerRank challenges. According to author we need to write code stubs in Rust.
