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: [[18, 7, 2, -50, 8], [8, 28, 32, 30], [13, -31, -9], [-8, 4], [21, 6], [15, -41, -1, -27, 44], [9, -39, -24], [-28, -18, -16, 9], [-45, 47, -44]]

SOLUTION: [-14400, 215040, 0, -32, 6, 44, -24, -8064, -44]
