Artemis: Refactor String and Vector Manipulation Methods for Performance and Readability

[artemis-gen-ai]

This pull request includes several refactoring changes across multiple classes to enhance performance and improve code readability. Key changes include:

1. String Manipulation: Refactored reverse and isPalindrome methods in the Strops class to utilize StringBuilder for efficient string reversal and enhanced palindrome checking logic using two pointers.

2. Single Class Methods: Optimized sumRange with a mathematical formula, added input validation in maxArray, and simplified sumModulus by removing unnecessary data structures.

3. DsLinkedList Methods: Improved shuffle and slice methods by leveraging built-in Java functionalities for shuffling and slicing, resulting in cleaner and more efficient code.

4. DsVector Class: Replaced manual implementations in sortVector, reverseVector, rotateVector, and mergeVectors with Java's Collections utilities to enhance performance and reduce code complexity.

5. Vector Initialization: Optimized the generateVector method by pre-allocating the capacity of the Vector, improving performance during element addition.

These changes collectively lead to cleaner, more efficient, and safer code, making it easier for future developers to maintain.
