https://nados.io/question/populating-next-right-pointers-in-each-node | |
Question Statement: | |
You are given a perfect binary tree where all leaves are on the same level, and every parent has two children. The binary tree has the following definition: | |
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. | |
