Easy
Topics
Companies

Given a binary tree, find its minimum depth.

The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node.

Note: A leaf is a node with no children.

 

Example 1:

Input: root = [3,9,20,null,null,15,7]
Output: 2


Example 2:

Input: root = [2,null,3,null,4,null,5,null,6]
Output: 5


 

Constraints:

The number of nodes in the tree is in the range [0, 105].
-1000 <= Node.val <= 1000
