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: [[35, 31], [28, -22, -14, 10, -5], [49, 49, -24], [17, 30, 16, -13], [-4, 12, 11, 24, -37], [49, -29, 45, 39], [-32, -10], [28, 45], [34, -28, -11, -6], [31, -10], [-14, -8], [-30, 39, -31, 22, -30]]

SOLUTION: [0, 86240, -24, 480, -1152, 0, 320, 28, 5712, -10, 112, 19800]
