Given the roots of two binary trees
q, write a function to check if they are the same or not.
Two binary trees are considered the same if they are structurally identical, and the nodes have the same value.
Input: p = [1,2,3], q = [1,2,3]
Input: p = [1,2], q = [1,null,2]
Input: p = [1,2,1], q = [1,1,2]
- The number of nodes in both trees is in the range
-104 <= Node.val <= 104
