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: [[0, -32], [-6, -5, 37, 6], [13, -33, 47, 44], [8, 35, 19, 48], [35, 48, 35, -42], [11, -35], [-2, -43, 12, -10, -17], [-6, -24, 31], [-12, -14, -48, -36]]

SOLUTION: [0, -36, 44, 384, -2016, 0, 240, 144, 290304]

PROBLEM: [[-38, 2, 1, 3], [43, -2, -1], [-18, 23, 27, 8, -3], [19, 26, -35], [31, -44], [16, 34], [-2, -18, -42], [39, -24, -50, -31, -18], [-1, -49, -11, 31]]

SOLUTION: [-76, -2, -144, 26, -44, 544, -1512, -21600, 0]

PROBLEM: [[-25, 42, 40, 41], [44, 22, 29], [21, 21], [-41, 7, 11, -46, -45], [50, -26], [43, -32], [42, 3, -20, 31], [-5, 12], [42, 20, 34, 50, 21], [19, -13, 24], [34, -17, 34, -6]]
