what problem are you facing in this question?

#6

@aa1 i understand the logic but how we can print the subtreess like it is shown in output
Input: root = [1,2,3,4,null,2,4,null,null,4]
Output: [[2,4],[4]]

we dont need to take care of printing it, we are just creating the arraylist and returning it
the driver function will handle it itself

@aa1 root values or root node
