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, 25, -4, -14], [48, -13, -2], [-9, -40], [29, 32, 8, 44], [-1, -8], [20, 31], [-44, -16], [-44, 40, 44], [29, -21], [40, 46, -5, 27, 20], [-14, -36, 31, 50], [36, -39], [39, -22, 36, -39, 34]]

SOLUTION: [-560, -96, -40, 11264, -8, 20, 704, -77440, 0, 36800, 25200, 36, -26928]

PROBLEM: [[-1, 49, 13], [2, 16, 6, 43], [36, -13, 9, 30, -48]]

SOLUTION: [0, 192, -51840]

PROBLEM: [[7, 48, 9, -11, -34], [-6, 10], [48, 19, -46, -38], [38, -35, 47, -31, -42], [41, 42, 27, 42, 3], [-8, 16, -18, 43, 24], [-30, -17, 36], [-18, 35, -4, 42], [-31, -50, -25, 29], [44, -42, 33, -40], [13, -23, -43, -5, 33], [5, 8, 38], [-13, -18], [21, 17, -50, 34, -12], [41, 26, 45, 48]]
