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: [[-33, 49, 15, 3], [49, -36, -17], [-5, 18, -4], [39, -24, 1, 49, -14]]

SOLUTION: [0, -36, -72, 336]
