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: [[26, 8, -46], [-40, -32, -24], [50, 11], [-29, -46, -8, 5], [-33, 43], [30, -2, -48, 13], [-22, -17, -20], [-9, -39, 21, 8, -42], [18, 12], [-49, -33, -21, -31, 37], [-42, 6, -5, 44], [-17, -44]]

SOLUTION: [-9568, -30720, 50, 368, 0, 2880, 440, -336, 216, 0, -11088, -44]

PROBLEM: [[38, 28], [-17, 24], [0, -7, -15, -8]]
