Removed redundant length checks and streamlined error handling for XOR operations. Simplified the loop to count differing bits by iterating directly over the XOR result. This improves code readability and reduces duplication.
Refactored the Evaluate function to utilize a new XOR helper for improved readability and modularity. The XOR function handles the bitwise operation, streamlining the bit difference calculation and supporting potential reuse in related computations.
Corrected a typo in a comment within `nilsimsa.go`. Introduced a new `Evaluate` function in `evaluate.go` to compute the bitwise difference between two Nilsimsa hash values, ensuring input validation and proper bit counting logic.
