I had to watch a video for this easy solution.

This is my own leetcode wrapped.

I should be ashamed for solving this question but hey, its on leetcode.

Add the same tree twice, check if the left side is same with the right side and if the right side is same as the left side recursively.

Think about it, when you look at the mirror, your left side becomes your right side and vice versa.

Valid Palindrome. #leetcode
