Teacher: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.
Teacher: Now, understand the problem? Solve this instance: [[-39, 22], [3, 40, 37, 21], [-39, 19, -32], [-19, 50], [-25, 21, -38, -40]]
Student:
[22, 40, -32, 50, 1520]
