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: [[-13, -41, 49], [-14, 24, 24, -44], [-10, -12, 26, -32, 38], [-1, -9], [-48, -31], [-5, 25, 33, -5, 7], [-23, -50, 38, 24, -5], [-17, -46, -9, 36]]

SOLUTION: [0, 354816, -3793920, 0, -48, 0, -45600, -1656]

PROBLEM: [[18, -39, -15], [-15, 23, 38], [-9, 37], [-16, -1, 28], [48, 3], [34, 19, -19, 46], [37, 26, -12, 12], [-37, -2, 0]]

SOLUTION: [18, 38, 0, -448, 48, 1564, -3744, 0]

PROBLEM: [[38, 32, 13], [18, 27, -26, 1, -35], [-42, 7, 21, -31], [-33, -15, 37], [2, 14, 38, 16, -37], [-41, -24], [49, 50, -30, -14], [-2, -12, -48], [23, 47, -30], [-9, -10, 5, 5, -19], [-50, -50, -11, 47, 17], [-49, 34, 7, -3, 21], [-6, -40, -41, 44, -36], [26, 27, -27], [38, 43, 14, -47, 47]]

SOLUTION:
[1216, -468, -42, 0, 17024, -24, 21000, -1152, -30, -10, 2500, 34, -380160, 26, 532]
