863 - All Nodes Distance K in Binary Tree.
Medium
Given the root
of a binary tree, the value of a target node target
, and an integer k
, return an array of the values of all nodes that have a distance k
from the target node.
You can return the answer in any order.
Example 1:
Input: root = [3,5,1,6,2,0,8,null,null,7,4], target = 5, k = 2
Output: [7,4,1]
Explanation: The nodes that are a distance 2 from the target node (with value 5) have values 7, 4, and 1.
Example 2:
Input: root = [1], target = 1, k = 3
Output: []
Constraints:
- The number of nodes in the tree is in the range
[1, 500]
. 0 <= Node.val <= 500
- All the values
Node.val
are unique. target
is the value of one of the nodes in the tree.0 <= k <= 1000
