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.

Example Input: [[21, 22, -31, -12, 29], [44, 20, 0, 26], [1, -33, 50, 4], [47, -35, 50, -31], [49, -26, 47, -36], [-39, -28], [44, 2, 13, 41, -9], [4, -14, -9, -20], [24, 35, -24], [-30, 45, 23, -17], [-18, 38, -29, 29], [-50, 13]]
Example Output: [-264, 0, 200, 50, 936, -28, 88, 1120, -576, -30, -684, -50]

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

Example Input: [[6, -50], [7, -15], [5, -45, 26, 43], [-4, 30, 16, 19], [-34, 7], [-15, 31], [36, -25, -42, 29, -36], [-14, 28, 10, 18, 49], [-37, -14, -25, -21, -14], [-50, 5, 30], [15, -43, 6, -3], [-7, -13], [32, 26, 48, 38, 44], [-32, -6, 40]]
Example Output:
[-300, 0, 26, -1920, -34, 0, 54432, -70560, 196, -1500, 6, 0, 66772992, 7680]
