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: [[21, 6, -29, 28], [14, 37, -4], [44, -23, 20, 39, -9], [-30, 28, 40, -9], [33, 45], [-45, 36, -4, -14]]

SOLUTION: [168, -56, 880, -33600, 0, 2016]

PROBLEM: [[44, 11, -29, -18], [4, 9, 48], [-31, -30, -29, 34], [-26, 24, 22, 34], [22, 38, 1, 17, -50], [27, -46, -25], [-1, 15, -40]]

SOLUTION: [-792, 192, -1020, -466752, -41800, -46, -40]

PROBLEM: [[45, 22, 1, 50, -1], [16, -14, 4], [-14, 15, -27], [32, -34, 6], [15, 48, -33, 49], [-45, 43, 43, 18], [47, 39, 8, -3, -36], [-35, -31, -34, 34], [13, -40, 2, 24], [-28, -41, 40, 35, 37], [-14, 32]]

SOLUTION:
[1100, -896, -14, -6528, 48, 18, -288, -1156, -1920, -1120, -448]
