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: [[-12, -42, -47, -30], [37, 29, -20, 46, -7], [-17, -43], [-16, -26, -5], [-18, 10], [-43, 26], [1, 23], [-22, 34, -4, -21], [-37, 25]]

SOLUTION: [-15120, -920, 0, 416, -180, 26, 0, 2992, 0]

PROBLEM: [[45, -24, 39, -5, 39], [13, 1, 17, 19], [-10, 7, -30, 49, 19], [20, 5, -46], [8, 11, -1, -45, -50], [-14, -42], [21, 33, 3, -34], [-2, 7, -46, 15], [41, -19, 40]]

SOLUTION: [-24, 0, 300, -920, -400, 588, -34, 92, 40]

PROBLEM: [[23, 40, -50, 25, -1], [12, 16, 34, 45, 44], [11, -42, 39], [22, 3, -21], [-44, 8, -23, 15], [28, -41, 27, 33, 16], [-30, 32, -24], [9, 19], [-11, 35, -37, -21], [0, 22], [21, 16, -3, -34, -13], [36, 39, -18, -24], [32, -46, 23, 37, -2], [3, 48, 1, 24]]

SOLUTION:
[-2000, 287232, -42, 22, -352, 448, 23040, 0, 0, 0, -544, 15552, 2944, 1152]
