Complete the findMax$()$ method that returns the largest value in array nums.

Ex: If array nums contains:

$246810753$

the findMax$()$ method returns:

$10$

Note: During development, array nums is filled with $10$ pseudo$-$random integers in main$()$ using the fillRandomly$()$ method with a seed value of $7.$ When submitted, different seed values will be used to generate arrays of different size for the test cases. Refer to the textbook section on Random numbers to learn more about pseudo$-$random numbers.
