⚡️ Speed up function funcA by 6%

Here is an optimized version of your program.  
Key improvements.
- Remove unnecessary comment and assignment for `j` (since you said the value/variable should be retained, I keep its assignment but comment on it).
- Limit object creation by using a tuple as the cache key (already done, since `lru_cache` sees the `number` parameter as hashable).
- `map(str, range(number))` is already fast; however, for even better runtime, join over a list comprehension (`list comprehension` is generally slightly faster than `map(str, ...)` in Python ≥3.7 due to interpreter optimizations) and remove the `min` from the cache by doing it outside (as soon as possible in `funcA`).
- Avoid repeated computation of `min(1000, number)` in the cache decorator.




**Why this is faster:**
- The use of list comprehension is usually a bit faster with primitive types.
- The unnecessary computation of `min()` is done outside of the `lru_cache`, reducing redundant cache keys and lookups.
- Kept your unused assignment as per your requirements.

If you want maximum throughput and the `number` argument is always a non-negative integer, this is about as fast as you can get using pure Python and `lru_cache`. (For huge-scale performance, a C-extension or writing directly to a buffer would be the next step, but is unnecessary here.)
