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: [[-6, -2, 20, 50], [31, -17, -31, -36, 39], [15, -26, -41], [21, -34, 50, -40, -36], [42, 22, -45, 32], [-39, 20, 31, 50, -36], [45, -1, -21, 44], [-2, 22, -17, 2, -22], [14, -49], [-12, 36, 40, 42, 41], [23, 32], [14, 13, 26, -39, 6], [32, -16, 7, 20, 5], [46, 29], [27, -44, -25]]
