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: [[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]

PROBLEM: [[-30, -27, 29], [30, -34, -5, 22], [5, 15], [21, -36, -50, -22], [36, 8], [-12, -36, 11, -6, -8], [-5, -5, 12], [39, 42, -35, -42], [28, 38, 8], [44, -10, -5, -22, -32], [-3, -48, 40, -33, -9], [-46, -25, 31, -21], [-28, -50], [-8, -46, 50, -10, -8], [-27, 2, 41, 19]]
