We’re back for episode 2 of our second series! Last series we completed the number of islands problem, and failed at Conway’s game of life as we were learning too much cool #rustlang. This time we’re back to work on a new set of problems. You can catch the previous episodes on the Microsoft Reactor YouTube channel:    • Crack code interview problems with Rust   Interviews for coders 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. In this series, ‪@jimbobbennett‬ is joined by Nell Shamrell-Harrington, a Principal Software Engineer at Microsoft and a member of the Rust board of directors. Our intrepid experts will try th …...more

Introducing Nell, and This Week in Rust

0:40

Are we seeing more rust jobs? Yes!

3:34

Game development in rust with Bevy.

7:07

We discuss tech jobs and interviews and how to prepare

13:32

The word search problem we are looking at today

24:54

We dive into the code starting with our test case and our rust code to iterate through the board

26:10

Breadth first vs depth first search

28:08

Building a recursive function to look for the next letter

Interview tip - write comments to plan your ideas as you code

36:20

String slices in rust to chop up our word

37:28

Adding guards to check if we have found our word

41:00

Subtraction from usizes, and signed and unsigned integers.

45:00

I'm now at the point with rust where I know if I see a red squiggly I should probably put an & in front of it

49:45

We run our test, and it works! Let's add more tests

55:08

The data structures and algorithms we used

57:48

We discuss the performance of our algorithm in big-O notation

We’re back for episode 2 of our second series! Last series we completed the number of islands problem, and failed at Conway’s game of life as we were learning too much cool #rustlang.

In this series, ‪@jimbobbennett‬ is joined by Nell Shamrell-Harrington, a Principal Software Engineer at Microsoft and a member of the Rust board of directors. Our intrepid experts will try their hand at a range of coding challenges in 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. Jim is new to Rust, so will be learning a load of tips and techniques as he pairs with Nell to solve these challenges. In the last episode we tried to implement solution to a word search problem, but we were having too much fun in the chat talking about rust so didn't get much further than a test case and looping through the board. In this episode we finally manage to complete the word search problem whilst talking rust, tech careers, interviews and more! 00:00 - Welcome! 00:40 - Introducing Nell, and This Week in Rust - https://this-week-in-rust.org/ 03:34 - Are we seeing more rust jobs?
