LeetCode 101. Symmetric Tree

Question : Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).

For example, this binary tree [1,2,2,3,4,4,3] is symmetric:

1
/ \
2 2
/ \ / \
3 4 4 3


But the following [1,2,2,null,3,null,3] is not:

1
/ \
2 2
\ \
3 3


Follow up: Solve it both recursively and iteratively.
