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: [[-6, -18, 49, 35], [16, 5, -12], [27, 39, -15, 29, 39], [41, 31, 16, 35], [-24, -30, 50, -42], [-8, -12, -29], [23, -41, -11, 23]]

SOLUTION: [108, -192, 0, 16, -1512000, 96, 0]

PROBLEM: [[-11, -13, 7, 45, 46], [-5, -20], [6, -15, -6, 17, 26], [46, 26, -25, -47], [-18, -12], [30, -22], [4, 32], [-43, -26], [6, 4, -2, -32], [21, -26, -36, 41], [-14, 24, -31], [20, -16, -15, -50], [50, 30, 5, 46], [-25, -15]]

SOLUTION: [46, -20, -936, 1196, 216, -660, 128, -26, 1536, 936, -336, 16000, 69000, 0]
