WebFeb 7, 2024 · What makes this confusing is that being a reverse lookup, the "index" is also what you consider the values (and vice-versa with each "value" on the queue being an index into a. I used a queue because you only want to use each index once (so the pop is your equivalent to setting the value to \0).
