Welcome back to another week of solving algorithms on leet code. Today, we are going to be looking at a quick and easy algorithm that I think is perfect for beginners: Number of Good Pairs. The Problem The goal of this…

Welcome back to another week of tackling algorithms. Today, we are going to be looking at a leetcode problem called Self Dividing Numbers. …

I’m not going to lie: I clicked on this problem because I thought it would be easy. I mean, it’s just adding strings right? How hard could it be? Well, much to my surprise and, honestly, irritation, this problem was actually kind of challenging as adding large numbers without BigInt…

I feel like it’s been a while since I’ve actually sat down to solve an algorithm. I mean, it’s been over a week, which I guess is a long time on someone’s scale. Like a fly. A week is a very long time for a fly. I don’t really know…

Another week, another algorithm to solve… This week we are going to be tackling another LeetCode problem. The problem is called Matrix Diagonal Sums and while it seems quite easy, it has a few tricky elements that I think are definitely worth going over. …

Welcome back to another week of Hope explaining her problem solving strategy to the void. Today, we are going to be looking at another LeetCode problem called Replace All “?”s to Avoid Consecutive Repeating Characters. I actually really enjoyed the process of solving this problem and think some of the…

I’ve had a hectic week moving into a new place (fourth and last time this year!) and during the chaos my algorithm practice has fallen to the wayside. …

Today, I want to share one of my go-to algorithm solving techniques: hash maps. Hash maps are a data structure that go by many names. In Python, we call them dictionaries. In Ruby, they are just called hashes. And, in JavaScript, we call them objects. …

If you are a returning reader, welcome back! And if you are a first time reader, welcome! Today, we are going to be taking a look at another popular leet code algorithm: String Matching in an Array. I actually think this is a great problem for beginners and I wish…
