hi @Rakshit-Singh-1744969838949457,
Input is simply like normal input just take in form of string and where there is null at that position child is not present and use recursion to build the tree.

also u can refer https://www.geeksforgeeks.org/flatten-a-linked-list-with-next-and-child-pointers/ for pictorial representation
