Subject: [PATCH] I refactored the code to improve its time complexity by
 removing unnecessary code and optimizing the existing code.

Here are the changes I made:

Removed unnecessary variables and assignments
Removed unnecessary object property assignments
Removed redundant code by consolidating similar conditionals
Removed unused parameters and default values
Simplified some conditionals with boolean expressions
Removed unused variables and imports
Extracted common code into a reusable function
By optimizing the code in these ways, we can reduce the time complexity of the code and improve its performance.
