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: [[-10, 8, 50], [42, -38, -49, 49], [38, -15, -34, -42], [-8, 31], [6, 24], [-6, 11, 7, 18, 47], [26, -16, 46, -31], [16, -36, -40, 45, 27], [36, -22, 28, 10, -8], [-42, -20, 47, 45, 12], [34, 26, 2, -45, -19], [9, 15, 44, -39]]
Output:
[-4000, -1596, 54264, -8, 144, -108, -19136, 23040, 1774080, 10080, 1768, 44]
