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: [[17, -39, 44], [5, -40, 1], [-37, -30], [-46, -4, 26, -5, -22], [28, 22, 9, 36, -48], [45, -24, -4, 15], [38, -30], [-7, -29], [-16, -17, 19], [-8, 36, 50], [-48, 1, -10], [8, -50, -2], [25, -18]]

SOLUTION: [44, -40, -30, -105248, -1064448, 96, -1140, 0, -16, -14400, 480, 800, -18]

PROBLEM: [[-20, -14, -39], [-47, -16, 27], [-46, -2, -34], [5, 28, -43, 26, 46], [35, -23, 19, -27], [7, 8, 28, 37, -23], [-41, -13]]

SOLUTION: [280, -16, -3128, 33488, 0, 224, 0]

PROBLEM: [[-47, -33, -47, -43], [17, 21, -14, 32], [9, -47], [38, -26, -2, -18, 42], [28, -13, -26, 15, 35], [-9, 46, 34, 41], [-9, 34, 38], [-40, -1, -5]]

SOLUTION:
[0, -448, 0, -1493856, -728, 1564, 1292, -40]
