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: [[1, 45, 21, -7, 5], [-23, 13, -21], [50, 35, -5], [-24, -2], [-43, 40], [34, 47, 26, -29, 23], [11, 43, 4, 45, 22], [4, -4, 0], [31, -8, 23, 24, -26], [42, -3, -29, 39], [42, -8], [-32, -6, -35, 45, -17], [-25, -21, -12, 31], [30, -20, -29], [-11, -3]]
Output:
[0, 0, 50, 48, 40, 884, 88, 0, 4992, 42, -336, 192, -12, -600, 0]
