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: [[-15, 35, 29], [-7, -17, 19], [-40, -37, -1, 47, -29], [-26, -3], [-16, -28, -13, -19], [38, -44], [-20, -14, 49, 44], [-33, -10, -37], [-11, 11, 26, 48], [-18, 32, 49], [-19, -36, -3, -45, 7]]

SOLUTION: [0, 0, -40, -26, 448, -1672, 12320, -10, 1248, -576, -36]
