Watch expert software developers solve interview problems in Rust! Interviews for software engineers often come with a coding challenge, using platforms like LeetCode or HackerRank. These challenges ask you to solve coding problems in a language of your choice, to show what algorithms and data structures you know, and highlight how you solve problems. Love them or hate them, being able to solve these kinds of challenges is becoming a part of interviewing for your next job. This series is all about how expert developers try (and possibly fail) to crack these coding problems using Rust, a powerful systems programming language that is rising in popularity, and has been rated as the most loved programming language for the past 7 years in the StackOverflow survey. In this show Jim takes on a classic coding problem - the number of islands problem. Jim is fairly new as a rustlang developer, so he has roped in Ryan Levick to help. Ryan is a seasoned  …...more
