Given the roots of two binary trees `root` and `subRoot`, return `true` if there is a subtree of `root` with the same structure and node values of `subRoot` and `false` otherwise.
|
|
|
|
A subtree of a binary tree `tree` is a tree that consists of a node in `tree` and all of this node's descendants. The tree `tree` could also be considered as a subtree of itself.
|
|
|
|
**Example 1:**
|
|
|
|
|
|
|
|
Input: root = [3,4,5,1,2], subRoot = [4,1,2]
|
|
Output: true
|
|
|
|
|
|
**Example 2:**
|
|
|
|
|
|
|
|
Input: root = [3,4,5,1,2,null,null,null,null,0], subRoot = [4,1,2]
|
|
Output: false
|
|
|
|
|
|
**Constraints:**
|
|
|
|
* The number of nodes in the `root` tree is in the range `[1, 2000]`.
|
|
* The number of nodes in the `subRoot` tree is in the range `[1, 1000]`.
|
|
* `-104 <= root.val <= 104`
|
|
* `-104 <= subRoot.val <= 104`
