Problem Statement Given a non-empty array of integers, every element appears twice except for one. Find that single one. Note: Your algorithm should have a linear runtime complexity. Could you implement it without extra memory? Thought Process My initial conclusion was that no, you couldn’t. Since there’s not a range for the possible numbers in the array and the array isn’t already sorted, you can solve in linear time if you used an object to store counts, but you need that extra storage or sorting is O(n log n).

For this second installment of Getting Going With Go, we’re going to cover slices – how to create them, how to add more elements to them, and how to retrieve the elements of them individually. We’ll also cover how what maps are in Go and how to create them.

Go Languages

After hearing a lot about the Go programming language and its similarity to C, I decided to finally get around to trying to learn it (I’m currently watching Brenna Martenson’s course on Frontend Masters, “Go for JavaScript Developers”). And since the best way to ensure you’ve actually learned a thing is to teach a thing, I decided to start this blog. So join me as I muddle through the early stages of learning a language.
