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: [[20, -33, 10, -36, 40], [-10, -34, 33], [-3, 40, 0, -41, 20], [13, -49]]

SOLUTION: [-288000, 340, 0, 0]

PROBLEM: [[-25, 37, -13, -24], [-31, -17, 9, -21, -41], [2, -41, 25, -42, 48], [-26, -36, -15, 33, 25], [41, 17, 45, 3], [37, -43, -30], [12, 27, -35, 7, -3], [33, -9], [22, -4, 43, 35], [-47, -46, -26], [23, -45, 2, -39], [6, 18, -29, 13, 13], [-9, -39], [3, -15, -11, 0], [-4, 17]]

SOLUTION: [-24, 0, -4032, 936, 0, -30, 12, 0, -88, 1196, 2, 108, 0, 0, -4]

PROBLEM: [[28, 37, -45, 22], [20, -15, -2, -33, 35], [-20, 13], [28, -49, -39, -22, 12], [-5, 32, 13, 19], [-12, 7], [36, -26, 26], [-12, 19, 47], [-5, -25, -35, 21, 48], [33, -4, -28, -10], [48, 1, 35, 37], [-24, -8], [5, -39, -46, -6, 0], [14, -32, -5]]

SOLUTION:
[616, -40, -20, -7392, 32, -12, -24336, -12, 48, -1120, 48, 192, 0, -448]
