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: [[-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]

PROBLEM: [[8, 27], [47, -6, -15, 5, 47], [-16, -48, 0, 37, -44], [-21, -20, 13, -47], [-38, -47], [-33, -19, 44, 24, 9], [47, -15], [-20, 5, -13, -18], [32, -27, 21, -34, 3], [-49, 38, 25]]

SOLUTION: [8, -6, 0, -20, -38, 1056, 0, 360, -1088, 38]

PROBLEM: [[-34, 23, 31, -49, 37], [-1, -30], [27, -50, 48, 28, 10], [44, 21]]

SOLUTION:
[-34, -30, -672000, 44]
