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: [[-46, -21, -24, -30], [-10, -50, 21, 5], [44, -45, 15], [8, -28, 6, -22], [-14, 42, -38], [-18, -35, -6], [-48, -13, -24, -36, -27], [49, 1]]
Output:
[-33120, 500, 44, 29568, 22344, 108, -41472, 0]
