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: [[-10, 31], [28, -27], [14, 19, -43, 33], [30, 0, -19], [14, 8, -41, 2], [-24, 48, -7], [41, 11, -5, 16], [-24, -9], [41, -35, 33, 19, -13], [41, -1, 36], [-16, -42], [16, -19, 0, 26, 5], [49, 9, 21, -35, -23], [49, -14, 1, -30], [29, -12, 20]]

SOLUTION: [-10, 28, 14, 0, 224, -1152, 16, -24, 0, 36, 672, 0, 0, 420, -240]

PROBLEM: [[29, -34, -34, 13], [-23, -1, -33], [-47, -7, 9], [26, -33, 23], [43, -39, -43], [2, -12, -38], [7, 45], [31, -3], [-35, -31, -30, 7]]

SOLUTION: [1156, 0, 0, 26, 0, 912, 0, 0, -30]

PROBLEM: [[-9, 7, -25], [11, 9, -24], [17, 37, -28, -50], [-50, 27, -20], [21, 36, 29, -16], [3, -22], [-11, -44], [-8, -50, 44], [3, -43, -18, -29]]

SOLUTION:
[0, -24, 1400, 1000, -576, -22, -44, 17600, -18]
