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: [[-36, -23, -48, -14, -27], [-26, 28], [-29, -37, -50, 31], [-11, 46], [8, -7, -16, 42], [43, -47, 8, 3], [0, 36, -48, 44, 49], [43, 31], [-12, -17], [47, 10, -48, 43]]

SOLUTION: [-24192, -728, -50, 46, -5376, 8, 0, 0, -12, -480]

PROBLEM: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[2, -21, -23], [18, -11, 49], [-1, -18, 2, -40, 25], [18, -46, 49, -22, -20], [-16, 47], [41, -3, -50], [34, 24], [25, 25, -1], [-11, -10, 15, 41], [-16, -34], [28, -8, 39, 46], [6, -15, 50, 36], [-11, -31, -17, -45, 31]]
