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: [[3, 18, 0, -30], [39, -17], [14, -13], [-37, 37], [23, 31, -22], [25, -10], [30, 40, -43, -43, 13], [30, -46], [7, 1, -33], [-50, -26, 12]]

SOLUTION: [0, 0, 14, 0, -22, -10, 1200, -1380, 0, 15600]

PROBLEM: [[7, -39, -8, -38, -50], [29, -39, -35, -40], [13, 2, -36, -37, -32], [12, -29, -22, 26], [-48, 35, -3], [4, 38, -42, 10]]

SOLUTION: [-15200, -40, 2304, -6864, -48, -63840]

PROBLEM: [[-34, -35, -17, 0, 24], [45, -3, 5, -49], [42, 4, -27, -25, 44]]

SOLUTION:
[0, 0, 7392]
