Root Equals Sum of Children
You are given the root of a binary tree that consists of exactly 3 nodes: the root, its left child, and its right child.
Return true if the value of the root is equal to the sum of the values of its two children, or false otherwise.
Example 1
10
/ \
4 6Input
root = [10,4,6]Output
trueThe values of the root, its left child, and its right child are 10, 4, and 6, respectively, and 10 is equal to 4 + 6.
Example 2
5
/ \
3 1Input
root = [5,3,1]Output
falseThe values of the root, its left child, and its right child are 5, 3, and 1, respectively, and 5 is not equal to 3 + 1.
Constraints
- The tree consists only of the root, its left child, and its right child.
- -100 <= Node.val <= 100
