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: [[-19, 2], [44, 6, -45, -5], [3, -39, 25, 17], [7, -16, 36], [31, -9, 44, 4], [26, -31], [45, 6, 40, 7, 40], [-11, 26, -36, 44, -9], [-42, -50, 46, -48], [-10, 21], [14, -47], [-10, -18, -4, 29], [-31, 29, -41], [-31, 30]]
Output:
[2, 264, 0, -576, 176, 26, 9600, -41184, -4636800, -10, 14, -720, 0, 30]
