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, -50, -30, 3], [-28, -43, 2, -6, 13], [-11, -40], [23, -1, 20], [-14, -30, 7, -19], [16, -48, -28], [-33, -49], [40, 50], [-2, 31, 10, 21, 30], [-4, 39, -36], [-42, -43, -8], [-10, -32, 35], [-48, 15, -18], [-47, 31, -21], [-37, 10, -24]]

SOLUTION: [54000, 336, -40, 20, 420, 21504, 0, 2000, -600, 144, 336, 320, 864, 0, -240]

PROBLEM: [[7, 12, -50, 24], [-25, 29, 2, 42, -1], [-17, -33, 28], [-43, -46], [24, 19, 11, -27], [7, 13, -39, 18], [-19, -50, -21]]

SOLUTION: [-14400, 84, 28, -46, 24, 18, -50]

PROBLEM: [[-30, 1, -41, -29, 43], [45, 30, -11, 33, 40], [12, -9, -33, -5], [-3, 0, -4, 23, -32], [-37, -2, 26], [45, 36], [2, 37, -33, 42]]

SOLUTION:
[-30, 1200, 12, 0, -52, 36, 84]
