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: [[15, -20, -29], [-28, -45, -10], [27, -43], [33, 32, 1, 38], [-14, 5, 19, -3], [31, -30, -28, 20], [-33, -48, 22, -30, -46]]

SOLUTION: [-20, 280, 0, 1216, -14, 16800, -1457280]

PROBLEM: [[-30, -2, 30, 1, -2], [26, -44, -48, 43, 43], [-22, -14, -38, -40], [-36, 8, 23, 3, 37], [14, -49], [15, 4, 44], [18, -22]]

SOLUTION: [-3600, 54912, 468160, -288, 14, 176, -396]

PROBLEM: [[-20, 3, 41, 23, 38], [-15, 25, -34, 29], [-36, 16, -30], [-5, -50, 43], [49, -2], [3, 15], [21, -30], [-50, -37, 1, 16, -44], [17, -18, 16], [-5, 49], [0, -15, -5, -3, 40], [21, 19, 24], [38, 43, 22]]
