Welcome to our explanation of the find max function. This Python function takes an array as input and returns the largest number in that array. The algorithm uses a straightforward approach: it starts by assuming the first element is the maximum, then iterates through each element in the array, comparing it with the current maximum value. Whenever it finds a larger number, it updates the maximum. Finally, it returns the largest value found.
