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: [[-2, 41, -50, -30], [5, -47], [35, 6, -46, 21], [33, 23, -6, -26], [-46, -15, -2], [-16, 29], [-20, -12, -20, -50]]

SOLUTION: [-3000, 0, -276, 156, 92, -16, 240000]
