270. Subtree of Another Tree

EasyTree

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.

Examples

Input: [3,4,5,1,2] [4,1,2]

Output: true

Explanation: The subtree rooted at the left child (4 with children 1 and 2) equals subRoot.

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].
  • -10^4 <= root.val <= 10^4
  • -10^4 <= subRoot.val <= 10^4
