- * 1315. Sum of Nodes with Even-Valued Grandparent
- *
- * Given a binary tree, return the sum of values of nodes with even-valued grandparent.
- * (A grandparent of a node is the parent of its parent, if it exists.)
- * If there are no nodes with an even-valued grandparent, return 0.
- *
- * Example 1:
- *                          6
- *                        /  \
- *                       7    8
- *                      / \  / \
- *                     2  7 1   3
- *                    /  / \     \
- *                   9   1 4     5
- *
- * Input: root = [6,7,8,2,7,1,3,9,null,1,4,null,null,null,5]
- * Output: 18
- * Explanation: The red nodes are the nodes with even-value grandparent while the blue nodes are the even-value grandparents.
- *
- * Constraints:
- * The number of nodes in the tree is between 1 and 10^4.
- * The value of nodes is between 1 and 100.
