Improving the efficiency of the 'mod_inv' method within the 'mathsHelper' class. Currently, it uses a brute-force approach to find the modular inverse, which may not be optimal for large values of 'm'. Instead, we can utilize the Extended Euclidean Algorithm to compute the modular inverse more efficiently. #794

replaced the previous brute-force approach with the Extended Euclidean Algorithm to compute the modular inverse efficiently.
The function returns the modular inverse of a mod m if it exists, or None otherwise.
