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: [[-5, 22], [-37, 18], [2, -32, -20, 10], [40, 45, -14, 5], [27, -5, -36, 22, -1], [2, -27, -38, 41], [-41, -16, -12, 18, 11], [17, -45, 23, -49]]

SOLUTION: [22, 18, 12800, -560, -792, -76, 3456, 0]

PROBLEM: [[40, -27, 50, -24], [17, 8, -49], [-10, 48, -1, 28, -36], [13, -42], [-27, -11, -45], [-24, -11], [14, -10, -33, -1, -26]]

SOLUTION: [-48000, 8, 483840, -42, 0, -24, 3640]

PROBLEM: [[39, 34, 32, -8], [-46, -25, -9, 27, -2], [-12, 3, -27, -6, -49], [25, 36, 38, -38], [14, 14, -5], [-48, 26, 32], [11, -19, -16, 33], [1, 39, -48]]

SOLUTION:
[-8704, 92, 72, -51984, 196, -39936, -16, -48]
