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: [[-10, -9, 41, 48], [25, 31, 28], [21, -40, 14], [-12, 34, -32, -37], [30, -45, 21, -4], [15, -23, -49, 50, 30], [33, -9, -13]]

SOLUTION: [-480, 28, -560, 13056, -120, 1500, 0]

PROBLEM: [[-27, 50, 36, 5, 26], [-1, -12, -18], [0, -50, -50, 25], [-10, 8], [-12, -10, 16], [-3, -46, -6, -26]]

SOLUTION: [46800, 216, 0, -80, 1920, -7176]

PROBLEM: [[17, -12, -28, 50], [0, -45, 37], [41, 34, -50], [-25, 42, 19, 48], [22, -13, -45], [-9, -30]]

SOLUTION:
[16800, 0, -1700, 2016, 22, -30]
