230. Kth Smallest Element in a BST
Given the root
of a binary search tree, and an integer k
, return the kth
smallest value (1-indexed) of all the values of the nodes in the tree.
Example 1:
Input: root = [3,1,4,null,2], k = 1
Output: 1
Example 2:
Input: root = [5,3,6,2,4,null,null,1], k = 3
Output: 3
Constraints:
- The number of nodes in the tree is
n
. 1 <= k <= n <= 10^4
0 <= Node.val <= 10^4
