Q. The two Binary Trees are said to be similar if they are both empty or if they are both non- empty and left and right sub trees are similar. Write down an algorithm to determine if two Binary Trees are similar.
Ans:
We assume that the two trees are tree1 and tree2. an algorithm to determine if two Binary trees are similar or not is as follows:
similar(*tree1,*tree2)
{
while((tree1!=null) && (tree2!=null))
if((tree1->root) == (tree2->root)) similar(tree1->left,tree2->left); similar(tree1->right,tree2->right);
elseif(tree->root!= tree2->node){printf("Trees
are not equal");
return;}
}
