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: [[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]

PROBLEM: [[22, -32, 44, -38], [43, 20], [9, -19, -29, 10, 46], [21, -17], [-1, 20, -16], [27, -34, 18, 28], [-2, 44, 39, 8], [1, 12, -31, -24], [-50, -13, -2, 2], [9, -39, 11, -6]]

SOLUTION: [1177088, 20, 460, 0, -320, -17136, -704, -288, 200, -6]
