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: [[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: [[38, 28], [-17, 24], [0, -7, -15, -8]]

SOLUTION: [1064, 24, 0]

PROBLEM: [[37, 23], [-49, 11, -40, -45], [19, -5, -44, 33], [34, -11], [-32, 25], [38, -35, -26], [23, -31, 28, -45, 42], [12, -3, -29], [-50, -11, -30, -40, 38], [26, 10, 42]]

SOLUTION:
[0, -40, -44, 34, -32, -988, 1176, 12, -2280000, 10920]
