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: [[47, 10, 41, -23], [42, 15, -48], [24, -22], [17, -22, -39], [-10, -48, -24, -31, 32], [45, 35, 13], [-29, 41, 46], [15, 15, -9], [-27, 16, 44, 0, -1], [-11, 1, 35], [-11, -40, 19, -11]]

SOLUTION: [10, -2016, -528, -22, -368640, 0, 46, 0, 0, 0, -40]

PROBLEM: [[-36, 13, 37, -31], [-3, -10], [18, 17, 36], [-11, 35, 27, 30, 37], [4, 8], [31, 38, -26], [-29, 5], [9, 14, 37, -17], [28, 47, 24, -20, -21], [21, -13]]

SOLUTION: [-36, -10, 648, 30, 32, -988, 0, 14, -13440, 0]
