+# 951. Flip Equivalent Binary Trees
+
+For a binary tree T, we can define a flip operation as follows: choose any node, and swap the left and right child subtrees.
+
+A binary tree `X` is flip equivalent to a binary tree Y if and only if we can make X equal to Y after some number of flip operations.
+
+Given the roots of two binary trees root1 and root2, return true if the two trees are flip equivalent or false otherwise.
+
+
+

+Flipped Trees Diagram
+Input: root1 = [1,2,3,4,5,6,null,null,null,7,8], root2 = [1,3,2,null,6,4,5,null,null,null,null,8,7]
+Output: true
+Explanation: We flipped at nodes with values 1, 3, and 5.
+```
+### Example 2:
+```
+Input: root1 = [], root2 = []
+Output: true
+```
+### Example 3:
+```
+Input: root1 = [], root2 = [1]
+Output: false
+```
+
+### Constraints:
+```
+The number of nodes in each tree is in the range [0, 100].
+Each tree will have unique node values in the range [0, 99].
+```
