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: [[41, -50, 6, -16], [-16, -11, 12, -20, 14], [-39, -21, -43], [-34, -37, -6, -2, 23], [-3, -30, -39], [28, 28], [42, 15, -8, -19], [-41, 29]]

SOLUTION: [4800, 53760, 0, -408, -30, 784, -336, 0]

PROBLEM: [[-21, -12, -13], [-37, -23, -6, -17], [14, -14], [23, 22, 34], [23, 15], [42, -42, 31, -50], [22, 44, -8, 13, -20]]

SOLUTION: [-12, -6, -196, 748, 0, 88200, 154880]

PROBLEM: [[2, -35, -13, -30], [27, -19, -31], [-41, 21], [-42, 45, -12], [-38, -36, -38], [-27, -31, 32], [13, -44, -44, -32, -1]]

SOLUTION:
[-60, 0, 0, 504, -51984, 32, -61952]
