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: [[3, 18, 0, -30], [39, -17], [14, -13], [-37, 37], [23, 31, -22], [25, -10], [30, 40, -43, -43, 13], [30, -46], [7, 1, -33], [-50, -26, 12]]

SOLUTION: [0, 0, 14, 0, -22, -10, 1200, -1380, 0, 15600]

PROBLEM: [[-21, 0, -33], [38, -39], [38, -33, 6, 45], [48, -37, -34], [-46, -46, -30], [-13, 2], [-20, -37, 36, -28], [50, 0, -43, -20], [-50, -42, 14], [-13, -5, -30], [-45, -29, -37, -43], [3, -9, -44, 44, 28], [41, -25]]

SOLUTION: [0, 38, 228, -1632, -63480, 2, 20160, 0, 29400, -30, 0, -54208, 0]

PROBLEM: [[-18, -17, 23], [-8, 17, -15, 33, -26], [10, -16, -17, 35, -45], [27, -19], [22, -25, -50, -30], [-3, 26], [42, 12, 27], [-12, 15, -44, 5], [16, 48, -6], [-46, 41], [-32, -3, 9, -40, -43]]

SOLUTION:
[-18, 208, -160, 0, 33000, 26, 504, 528, -4608, -46, 1280]
