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: [[46, 24, -17, -8], [4, -20, -4], [26, -23, -33, -49, 26], [-45, -49, 17], [37, 41, 47, 23], [43, 9, -13], [50, 38, 49, 48, 33], [4, -39, -20, 32], [36, 36, 43], [1, -18, -13, -30], [-39, -3, -23, 11], [37, -25, -21], [-41, 33, 7, 36], [-22, -18]]
