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: [[-45, 37, 30], [-39, 24, -6, 26, -23], [18, -17, -15, 38], [-2, 25, 37], [24, 14, 13], [14, -15, 9, 46, 33], [-50, -47, 35, 19], [-8, -25, -14, -32, 12], [22, 22, 50, -21, 34], [48, -22], [41, 41], [33, 48, -20, 15, 13]]

SOLUTION: [30, -3744, 684, -2, 336, 644, -50, -43008, 822800, -1056, 0, -960]

PROBLEM: [[18, -39, -15], [-15, 23, 38], [-9, 37], [-16, -1, 28], [48, 3], [34, 19, -19, 46], [37, 26, -12, 12], [-37, -2, 0]]

SOLUTION: [18, 38, 0, -448, 48, 1564, -3744, 0]
