​We'll be going over slightly more challenging graph algorithms around the topic of islands.

• ​Island Perimeter - (Easy) https://leetcode.com/problems/island-perimeter/description/

• ​​Number of Islands - https://leetcode.com/problems/number-of-islands/description/

• ​​Max Area of Islands - https://leetcode.com/problems/max-area-of-island/description/

​If you are rusty, feel free to backtrack to linked list problems. We've all been there! We'll do what we always do best: coffee and algorithms, face to face conversations, and lots of whiteboarding!

​​Minimal screens! Lots of whiteboarding! Hopefully we'll spin out a Swift Playground or pretty Jupyter Notebook by the end of the session.

​What We'll Do

​​​Focus will be on implementation of an interesting algorithm, and testing to see how effective it is. We'll be implementing in python but with no screens, just whiteboarding :)

​​TIPS AND TRICKS

​​​​This is for people of all levels, since everyone is at all levels of practice. If you’re rusty on graphs, then start on your trees, and if you’re rusty on your trees, then brush up to linked lists.

​​If at any point you’re lost just speak up! Just work your way backwards if you get confused or are rusty! We did this with Jade at the algebraic data types workshop in Rust at our women and non-binary hacknight.

​MAKE ALGORITHMS MEANINGFUL AGAIN

​​​​We think that programming is inherently fun, more fun than most any game. It pushes our minds and gives us fundamentals to tackle bigger problems. Algorithms are also great for learning new ways of doing things in different programming languages.

​​​​Somewhere along the way job interviews have made algorithms a joyless, high stakes exercise 🙁 . A lot of us never get to use algorithms in our daily work anyway, and they’re just plain fun.

​

​​​BUT CAN ALGORITHMS BE ART?

​​​​Ideally you should be able to put your studies in a notebook. A few year ago one of our SudoRoom members even drew graph theory and cliques on the sidewalk around the neighborhood in a nearby park.
