Part 1. Definition
In this task you will be given a list of lists, of numbers. For every inner list, you should multiply every number in that list and put the results in your answer. The output should be a list of numbers with the same length as the number of the lists in the input list.
Part 2. Example
[[5, 1, 2, 7], [0, 4, 6, 6], [7, 8, 10, 3, 1], [1, 4]]
Answer: [70, 0, 1680, 4]
Explanation: The second list had zero so the second product is zero. Every product is calculated correctly: 5x1x2x7= 70, 7x8x10x3x1=1680, 1x4=4.
Part 3. Exercise
[[-22, -37], [-26, 34], [46, 43, 41, -49], [31, 32, -16, -7], [-21, -12]]
Answer:
[814, -884, -3973802, 111104, 252]
