Several months back I read what quickly became one of my favourite books of all time, The Happiness Advantage, by Shawn Achor. The reason I loved it so much? It did something I didn’t think possible: it quantified happiness. Now, quantifying things is something my number-minded brain loves. I can’t…

Having recently undergone an acquisition, I was tasked with the fairly standard post-merger task of migrating our existing codebase over to the new parent company. Luckily for me, both sides used Git. Unluckily for me, one side used GitLab (us), and the other used GitHub (them). Now, given that both…

In the world of programming, there are many ways to sort data. For the average engineer, you might just use .sort(), perhaps with a slightly modified sorting function to return your data in a specific way. But that’s probably about the most you do. If however you’ve ever taken an…

In this LeetCode problem, we’re given an array of numbers, and a target. Our job is to come up with every possible unique way to make that target by adding the numbers in the array. …

To be honest, this question is a little too simple. Thanks to the question guaranteeing that you won’t be given the tail node of a Linked List, there aren’t even any edge cases to handle, so the solution comes in at a whopping 2 lines.

In this LeetCode problem, we’re given a Linked List, and asked to determine whether or not it (or rather, its values) represents a palindrome. Revision point 1: A linked list is a data structure that consists of two properties; next which points to the next node in the list, and…
