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: [[-49, 2, 10], [-8, 18, -35], [0, 21, -23, -40], [10, 27]]

SOLUTION: [20, -144, 0, 10]

PROBLEM: [[13, 26], [42, -26, 21], [29, -39], [-24, 18, -17, -10, -17], [20, -3], [-15, -41, 17, -20, 16], [-6, 17, 14, -13, -4], [38, -39, 48, -46], [36, 1], [27, -45]]

SOLUTION: [26, -1092, 0, 4320, 20, -320, 336, -83904, 36, 0]

PROBLEM: [[2, 42, -25, 44], [-39, -27, -15, -44], [26, 12, 25], [-45, 28, 37, 8], [19, 26, -47, -17, 31], [-36, -44, 4, 16], [-11, -44, -39, -1], [36, 11, 38, -25], [9, -32, -37], [47, 48, 21, 29], [-47, 6, -23, 41, -49], [-4, 7], [37, -36, 3, -24], [39, -20], [-5, -18, 25, -7, 39]]

SOLUTION:
[3696, -44, 312, 224, 26, 101376, -44, 1368, -32, 48, 6, -4, 864, -20, -18]
