The implied assumption here is that if you can figure out the number of anagrams that can be made from a given string in just 30 minutes, you probably are smart enough to set up a web server in a couple of days with documentation and ChatGPT to guide you.

While the above sounds sarcastic, honestly, it isn't as ridiculous of a thought as it sounds. I don't think being good at DS&A problems guarantees that you're a good coder, but in general, the people who get good at these problems are also great coders. I can think of less than a handful of people who are good at CS problems but bad at actual coding.
