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, 7, 20], [-30, 36, -7, -19], [-37, -22], [25, 13], [22, -31], [18, 33, -17, -3, -30], [37, -33, 40, 14, 13], [11, -16]]

SOLUTION: [20, -1080, -22, 0, 22, -540, 560, -16]

PROBLEM: [[-27, -15, -29], [-30, 44, 42, -2, 31], [-20, -21], [49, 36, 49], [-36, -45, 44, -47, -34], [41, 37, -29, 23, -42], [25, 46, -12, 49, -49], [-22, 1], [-3, 21, -20, -48], [-39, -9, 26, 22]]

SOLUTION: [0, 110880, -20, 36, 53856, -42, -552, -22, 960, 572]

PROBLEM: [[18, 30, -7], [48, -41, -2, 25, 13], [0, 5, -26], [-30, -10, 45, -44], [23, 26, -33, -37], [31, -46, -48, -38, -36], [-25, 22, -20]]

SOLUTION:
[540, -96, 0, -13200, 26, 3020544, -440]
