Inputs

values is a list of 0 to 14 whole numbers, each from -30 to 30.

Create an empty list maxes.
Use a loop over values. After looking at each number, add the largest number seen so far (including this one) to maxes.
Complete runningMax so it returns maxes. Return it, do not print it.

With values = [3, 1, 4, 1, 5, 2], runningMax returns [3, 3, 4, 4, 5, 5].

TEST DATA 1: values is [3, 1, 4, 1, 5, 2]

TEST DATA 2: values is []

Put an if inside the loop to keep, skip or change items. Filtering, mapping and comparing neighbours show up in nearly every array question.
