I think I'd agree, but my argument is that going from a medium problem solved "pretty easily in a bad way" to a "fully optimized and efficient way" is easier than most people think. There's only a dozen or so patterns needed. As an example, if you know the two pointer technique (https://algodaily.com/lessons/using-the-two-pointer-technique https://algodaily.com/lessons/using-the-two-pointer-techniqu...), you're well on your way to solving at least 1/3 to half of array problems in a performant manner.

Some friendly feedback: I clicked through to your article about the two pointer technique and, AFAICT, there's nothing for me to do or read here. It says "In this guide, we'll cover..." but it's not clear how to actually view the guide. I'm guessing - without having clicked around at all - that my next step would be to create an account and visit the page again, but that's not at all clear to me as an unauthenticated user. I do see a small "Login" on the bottom right of the page, as well as "Sign in" and a highlighted "Upgrade" at the top. But there is no CTA telling me what my next step should be. Maybe users of your site who land on this page will know what that step should be, but you might want to add some direction for people who randomly land on it via SEO/SEM or links on forums. Cheers! ETA: in a search for some action, I clicked all over the graphic and on a couple phrases in the intro to see if they would take me somewhere. If you're tracking clicks, it might be worth looking at whether other users are doing similar things.

  I had the same experience; at the very bottom of the screen are "next" and "back" buttons. But it took me a while.

  Thanks so much for the heads up :-) It's amazing how much of the user's perspective you miss when you're heads-down in code all day. I've added some navigational indicators to hopefully make it a little clearer that you can press the footer buttons or swipe on the screen. Appreciate the friendly feedback!
