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: [[-20, 30, -4, 11, -28], [-17, 29, -20, -49, -22], [-21, -23, 0, -4, -16], [-27, -14, 37, 33, 9], [31, -39, 22, -20, -37], [32, 1, -1], [-45, -12, -36], [-50, -50, -6], [2, 5, 42, -24], [0, 48, -22], [-20, -8]]

SOLUTION: [-67200, 440, 0, -14, -440, 32, 432, -15000, -2016, 0, 160]
