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: [[12, -6, -21, 33], [-8, -29, -44, 38], [-45, -21, 18], [8, -17, -26, 50], [0, 18, -38], [2, -24], [-8, 34, 25, -10]]

SOLUTION: [-72, 13376, 18, -10400, 0, -48, 2720]

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]
