Q1. Flatten a binary tree
Ans. 
Flatten a binary tree by converting it into a linked list in-place.

• Traverse the tree in a pre-order manner and keep track of the previous node.

• Set the left child of each node to null and the right child to the next node in the linked list.

• Example: Input: 1 -> 2 -> 5 -> 3 -> 4 -> null, Output: 1 -> null -> 2 -> null -> 3 -> null -> 4 -> null -> 5 -> null

Q1. Delete nth node from end in linked list
Ans. 
To delete the nth node from the end in a linked list, we can use a two-pointer approach.
• Use two pointers, one to traverse the list and another to keep track of the nth node from the end.

• Move the second pointer n steps ahead of the first pointer.

• When the second pointer reaches the end of the list, the first pointer will be at the nth node from the end.

• Adjust the pointers to delete the nth node.
