I have a question for the following scenario;
I have n-number arrays in an ArrayList. The number of arrays is not predetermined, while the size of the array is fixed but it can contain null elements in it and the null values are considered as zero. I need to get the sum of each cell into the corresponding index in the new array, whose size is logically same as other arrays.
I tried to depict the scenario as follows;
I have a solution with classical way of iteration but I end up with a very dirty implementation. I would be happy to see your solution for this problem (preferably with Stream api)
