+<p>Does it look similar to you? So how did we get there?</p>
+<p>I started with a naive implementation of the original. First, we don&apos;t need the codepoint calculated and extracted for our validation function. We just want to know the data is valid, so we only need to calculate the next state. Then, the only thing we needed to be careful about was that tuples are 1-based, and that we need to stop processing the binary when we get the state 1 or when the binary is empty.</p>
