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.
One example: [[5, 1, 2, 7], [0, 4, 6, 6], [7, 8, 10, 3, 1], [1, 4]]
Solution is here: [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.

Now, solve this: [[31, -49, -25, 49, 17], [-2, -25, -9, 16], [10, 16, -39, 31], [-21, 48], [-7, 13, -21, 27], [35, 50, -42], [35, 45, 14, 21, -44]]
Solution:
[31633175, -7200, -193440, -1008, 51597, -73500, -20374200]
