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: [[-5, -24, 16, -14, 15], [17, 43, 1], [-49, 17, -27, -18, -24], [49, -31], [-12, 13, 49], [48, 17, 45, 44, -47], [-21, 23]]

SOLUTION: [5376, 0, 432, 0, -12, 2112, 0]
