Same Tree

Given two binary trees, write a function to check if they are equal or not.

Two binary trees are considered equal if they are structurally identical and the nodes have the same value.

C++:
01 bool isSameTree(TreeNode *p, TreeNode *q)
02 {
03      if((p==NULL)&&(q==NULL))
04           return true;
05      if(p==NULL)
06           return false;
07      if(q==NULL)
08           return false;
09      if(p->val!=q->val)
10           return false;
11      if(isSameTree(p->left,q->left)==false)
12           return false;
13      if(isSameTree(p->right,q->right)==false)
14           return false;
15      return true;
16 }
