**Notes:**
- Comments kept for the relevant explanations.
- `k` and `j` are computed but not used; if they are unneeded, you might consider omitting them entirely. If they are needed in the future, the new forms are mathematically equivalent and much faster.
- The use of `map(str, ...)` speeds up the join operation compared to a generator expression.
