Instructions: 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.
Input: [[-15, -35], [-14, -19, -40, -5, -14], [47, 15, -27, 15, -48], [0, 11, -22, -42, -35], [-19, 28, -15, 4, -6], [-23, 1], [31, 49, -38, 11, -30], [10, -32, 38, 30, 8], [12, 40, 19], [-13, -17, 14, -12], [-45, 27, 29, 5, -27], [-34, 43, -22, 31, 46], [19, 39, 8], [14, 31], [0, 47, -3, 32, -19]]
Output:
[0, -7840, -48, 0, -672, 0, 1140, -2918400, 480, -168, 0, 34408, 8, 14, 0]
