Question:117. Populating Next Right Pointers in Each Node II

Given a binary tree

struct Node {

int val;

Node *left;

Node *right;

Node *next;

}

Populate each next pointer to point to its next right node. If there is no next right node, the next pointer should be set to NULL.

Initially, all next pointers are set to NULL.



Approach: BFS Traversal

Use breadth-first search to connect next right pointers in each node of a binary tree. Use a queue to process nodes level by level, updating the 'next' pointers accordingly. The logic ensures that each node's 'next' pointer points to the subsequent node in the same level



Time complexity is O(N)

Space complexity is O(W),W is the maximum width of the tree at any level
