TASK DEFINITION: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
PROBLEM: [[-27, 50, 36, 5, 26], [-1, -12, -18], [0, -50, -50, 25], [-10, 8], [-12, -10, 16], [-3, -46, -6, -26]]
