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, 48], [-4, -24, 6, 12, -47], [-39, 18], [48, 29, 28], [0, -9, -13, -2], [6, -9, 1, 47], [44, 40, 17], [-32, -22, -31, -10], [41, 32, -37, 20, -21], [3, -37, -48, -1, -28], [6, 41], [4, 21, 45, 41, -32], [-44, 39, -11], [43, -36, 17], [1, -15, -34, -31, 46]]

SOLUTION: [48, 6912, 18, 1344, 0, 6, 1760, -7040, 640, 1344, 6, -128, -44, -36, -1564]

PROBLEM: [[-5, 22], [-37, 18], [2, -32, -20, 10], [40, 45, -14, 5], [27, -5, -36, 22, -1], [2, -27, -38, 41], [-41, -16, -12, 18, 11], [17, -45, 23, -49]]

SOLUTION: [22, 18, 12800, -560, -792, -76, 3456, 0]

PROBLEM: [[21, 4, 27], [-40, -46, -26, -10], [-31, 11, 48], [32, 5], [13, -37, 15, -31], [-32, -16, 2, -39, 20], [48, -25], [25, -7, 8], [-33, 20], [40, -16, -5, -2, -17], [-25, -38, -43]]

SOLUTION:
[4, 478400, 48, 32, 0, 20480, 48, 8, 20, 1280, -38]
