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: [[-11, -41, -30], [-12, -45], [-5, -46, -44]]

SOLUTION: [-30, -12, 2024]

PROBLEM: [[-18, -8], [18, -46], [-1, -35, 2, -14, -43]]

SOLUTION:
[144, -828, -28]
