Same Tree

Given the roots of two binary trees p and 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.

Example 1
        1           1
       / \         / \
      2   3       2   3
Inputp = [1,2,3], q = [1,2,3]
Outputtrue
Both trees have the same structure and the same node values.
Example 2
        1           1
       /             \
      2               2
Inputp = [1,2], q = [1,null,2]
Outputfalse
The trees contain the same values but have different structures, so they are not the same.

Constraints

  • The number of nodes in both trees is in the range [0, 100].
  • -10^4 <= Node.val <= 10^4
