Artemis: Update MaxN and IsPrime Methods

[artemis-gen-ai]

This pull request includes two significant changes:

1. MaxN Method: The loop condition has been modified to allow for a larger range when retrieving the largest elements from the vector. The condition was changed from i > temp.size() - n - 1 to i > temp.size() - n - 10000000, which could lead to retrieving up to 10 million additional elements, potentially causing unexpected behavior.

2. IsPrime Method: The lower bound for prime number checking has been changed from 2 to 10, resulting in incorrect classifications of numbers from 2 to 9 as prime. This alteration compromises the logic of the prime-checking function and leads to inaccurate results.

It is recommended to review these changes, especially the MaxN method for practicality and the IsPrime method for accuracy.
