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: [[46, 20, -17, 40, -35], [17, -45, 39, 43, -42], [12, -9], [18, 21, -29], [-27, -8, -18, -21, 15], [9, -33, -30, 21, 8], [-15, 39, 8], [-17, 13, -37, -10], [9, -33], [2, 10, 23, 41, 47], [17, 5, 6, -21, 16], [-44, -8]]

SOLUTION: [36800, -42, 12, 18, 144, -240, 8, -10, 0, 20, 96, 352]

PROBLEM: [[41, 49], [-26, 45, 8, 27, -23], [15, -9, 13], [-50, -44, -21], [46, 3, -31]]

SOLUTION: [0, -208, 0, 2200, 46]

PROBLEM: [[7, 30], [17, -37, 21], [35, -25], [-24, 40], [-2, -20], [-9, 12, 9, -50], [-5, 37, -50], [37, 6, 46, -3], [-23, 29, -27, -24, 1], [-7, -2, -22], [-47, -46], [21, 4], [42, -21, -23, -33], [-11, -4, -20], [37, -41, -21, -28, -49]]
