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: [[-41, -1, 34], [-2, -32], [33, 38, 37, 2, 42], [39, -43, 39, -30], [-32, 48, -14, -10, 22], [4, 43], [-37, 47, -22, 34], [5, -43, 24, 3], [-26, 39, -15, -33, 49], [-31, -12, -17, -6], [-33, -18, 4, -49, -19], [-47, -15], [-12, 28], [1, -20, 19, 4, -13], [-30, -47, -6]]

SOLUTION: [34, 64, 3192, -30, -4730880, 4, -748, 24, -26, 72, -72, 0, -336, -80, 180]

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: [[11, -13, -31], [16, -33, -5, 16], [7, 33, 48], [10, -49, 35, 37, -20], [-17, 8, -17], [-16, 41, -1], [-23, -20, 7, 4, 28], [-21, -3, 16], [21, 47, 13], [-41, 26, -2], [15, -26], [47, 37, 44, 1], [-2, 24, 48], [13, -42, -18, 26], [20, -22]]

SOLUTION:
[0, 256, 48, -200, 8, -16, -2240, 16, 0, -52, -26, 44, -2304, 19656, -440]
