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: [[-42, -27, -46, -45], [45, -32], [-44, -8], [-23, 2], [15, 2, 17, 7], [27, 39, -38, -39, -9], [2, 46, 42, -33], [-47, 33, -50], [-9, -25, 8, 23, -1], [-46, -20, 27, 47, -10], [-13, 9, 22, 29, -40], [-45, -5, -30], [36, -20, -42], [-33, 39, -28, 20]]

SOLUTION: [1932, -32, 352, 2, 2, -38, 3864, -50, 8, -9200, -880, -30, 30240, -560]

PROBLEM: [[25, 34], [43, 2, 40, -25, -45], [16, -49, 40, 18]]

SOLUTION: [34, 80, 11520]

PROBLEM: [[-41, -7, 28, -26], [-47, -26, -10, -28, 49], [31, -48, -37, 8, -10], [4, -30, -38, -19], [-3, 18, 14, 44], [9, 1, -28], [50, 39, 27], [40, -4, 17], [1, -35], [13, 0, 26, 47], [13, 45], [-17, 46, 10, 9, 38], [22, 25, 36, 37, 6], [-11, 50, -14]]

SOLUTION:
[-728, -7280, 3840, 4560, 11088, -28, 50, -160, 0, 0, 0, 17480, 4752, -700]
