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.
Input: [[-15, -16, 18, 31], [-30, -39, -37, 11, -39], [42, -15], [-48, 29, -16, 38, -36], [7, 6, -24, 46], [28, 20, -26, 19], [-26, 0, 19, 27, 4]]
Output:
[-288, -30, 42, -1050624, -6624, -14560, 0]
