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: [[-43, -23], [20, -11, 28, -49, -12], [-4, 33, 23, 13], [21, -16, -12], [-50, -15, 6, 45], [31, -28], [5, 49, -31, -21], [-48, -44, -28, 36], [47, -33, -19, 14], [-26, -29, -24], [27, 41, -25, 45, 28]]

SOLUTION: [0, -6720, -4, 192, -300, -28, 0, -2128896, 14, 624, 28]
