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: [[-38, 48, 1], [-4, -35], [28, 26], [34, 38, -46, 23], [-3, -47, -1, 32, -41]]

SOLUTION: [-1824, -4, 728, -59432, 32]

PROBLEM: [[13, -25, 15], [10, -5, 19], [-30, 14, -11, 6, -9], [-8, 47, 50], [-47, 42, -36]]

SOLUTION: [0, 10, -2520, -400, -1512]

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]
