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: [[-41, 14, 27, -41, 50], [-42, 48, -8, 10], [50, 27, 21, -38], [0, -34], [24, 30, -22], [-35, 25, -15, -19, 46], [34, 21, 10, -24, 31], [29, 44]]

SOLUTION: [700, 161280, -1900, 0, -15840, 46, -8160, 44]
