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: [[-6, 49, 20], [-20, 8, -19, -9], [-21, 9, 15, -3, -36], [-46, 24], [11, 32, -12], [-38, -28], [-32, 17], [-46, -5, -39, -39], [-19, -9], [-49, 11], [43, 22, 28, -17, -40], [-23, 16]]

SOLUTION: [-120, -160, -36, -1104, -384, 1064, -32, -46, 0, 0, -24640, 16]

PROBLEM: [[-24, -7, -45, 20, 0], [6, -30], [-42, -13, -46, -7, -25], [-14, 18, -9, 49, 11], [27, -41, 12, 35], [-29, -44, -33, 17], [38, -48, -44], [-46, 42, 43, -3, -6], [-16, 48], [41, 31, -33, 31], [27, 47], [-22, 48, -24, -31, -32], [18, -19, 44, 42, 11], [-42, -16, -16]]

SOLUTION:
[0, -180, 1932, -252, 12, -44, 80256, 11592, -768, 0, 0, -811008, 33264, -10752]
