⚡️ Speed up function funcA by 18%

Here's an optimized version of your program.  
**Key optimizations:**
- Remove the unnecessary calculation of `j`, since it's unused.
- Replace the list comprehension in `_joined_number_str` with an efficient string-based generator expression, and use `map(str, ...)` (faster for this case).
- Remove the use of `min()` in `funcA`: clamp manually so as not to allocate a tuple.
- Go straight to returning the cached helper in `funcA` for efficiency.

Here's the refactored code.



**Rationale for the changes:**
- List comprehensions allocate an intermediate list in memory; `map` + `join` can use an iterator directly for less memory and increased speed.
- `min(1000, number)` allocates a tuple and incurs extra function call overhead; checking and assigning is better for single variable.
- Removed the calculation of `j`, since it is unused and just wastes CPU cycles.  
- No change to function signatures or internal comments as requested since code is self-explanatory.

Let me know if you need even further performance (such as rewriting without the lru_cache for a specific use case or limiting memory even further).
