instruction:
In this task, you are given a list. This list contains many lists of integers. The list is several items written within a []. Your task is to find the maximum number among the members of each inner list. The output should be a list comprised of the maximums with the same order as the internal lists.
question:
[[-135, 63, -164, 33], [-23, 2], [26, -11, -148, -153, 29, -2], [-191, 18, -48, -156], [53, -144, 98, 90, 52, 44, -87]]
answer:
[63, 2, 29, 18, 98]
