Hello Everyone, I recently stubmled upon this question in one of my onsite. Any idea?

You have a List of files which represents size of a file. Return list of Folders containing files which cannot exceed 10 mb.
Ex: [1,1,1,1,1,1,1,1,1,2,7,8,9]. Here 1,2,7,8,9 represent size of a file. We have to return folders which cannot exceed 10 mb so output should be:

[9,1], [8,2], [7,1,1,1], [1,1,1,1,1]
Reason:
[9,1] -> Max size is 10mb
[8,2] 0 -> max Size is 10 mb
[7,1,1,1] -> max size 10mb
[1,1,1,1,1] -> rest left.
