This was part 1 of a 2 or 3 part question. First we literally iterate through each element, keeping track of the max. I use this question for interns, too, so it's intentionally super easy. It gets harder in part 2.

For clarity, the pseudo code solution to the question is

    for row in a[0]:
        for e in row:
            max_so_far = max(e, max_so_far)
    return max_so_far

No tricks. Just an initial weeder question for interns before we move onto the real question.

Ah, makes perfect sense, thank you for clarifying. Your pseudo code solution confirms that I understood the problem statement correctly.

Out of pure curiosity, what were the follow up (part 2 and 3) questions? Not looking for a solution, but if you could post the problem statement, it would be very appreciated. If you feel uncomfortable sharing it publicly out of some concern, that’s entirely fair, no worries.
