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: [[-33, 46, 50, -16], [20, 27], [-31, 40, 45], [-20, 47], [-15, 23, 46, 30], [-46, -43, -42, -39, 2], [12, -50, -46], [8, 35, 28, -26], [-13, -35, -14], [21, 38, -1, 4], [26, 30, 44, -45], [10, -43], [-37, 38, -42]]
Output:
[-36800, 20, 40, -20, 1380, 3864, 27600, -5824, -14, 152, 34320, 10, -1596]
