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: [[-37, -41, 17], [29, -44, 35, -34, -46], [26, 9, 28], [0, -16, 24, -18], [13, 18, 42], [29, -21, -27], [-10, -16, 12, -39, -22], [4, -3], [-29, -23]]

SOLUTION: [0, -68816, 728, 0, 756, 0, -42240, 4, 0]

PROBLEM: [[40, 4, -24], [-27, 46, 10, 23], [32, 39, -12, 33, 13], [36, -48], [-25, -7, -28], [-16, -16, -10], [11, 24, 50], [13, -31, 39, -4, 8], [19, -19, 39, 3], [-34, 50], [-18, -35, -29], [-25, -28], [-41, 3], [-26, 34, 19, -37], [-33, -47, 18]]
