* Fix bug in multi-threading
- Multi-threading (despite being commented out) had a tiny bug: missing target argument (2nd argument).
- Commented out code was also slightly hard to understand, added (Option 1/2) in comments to clarify where a user may choose between 2 implementations.

* Update prefix_sum.py
Index Validation for get_sum
Raises ValueError if start or end is out of range or start > end.
Handles cases where the array is empty.
✅ Empty Array Support
If an empty array is passed, get_sum raises an appropriate error instead of failing unexpectedly.
✅ Optimized contains_sum Initialization
Initializes sums with {0} for efficient subarray sum checking.

* Fix And Add power.py
To fix the inaccuracies and allow handling of negative exponents and bases, the key issue lies in how negative numbers are handled in the power calculation, especially when dividing.
## Example Output:
```python
>>> power(4, 6)
4096
>>> power(2, 3)
8
>>> power(-2, 3)
-8
>>> power(2, -3)
0.125
>>> power(-2, -3)
-0.125
