Here is the modified version of Morris inorder tree traversal
algorithm<http://stackoverflow.com/questions/5502916/please-explain-morris-inorder-tree-traversal-without-using-stacks-or-recursion>
inordermorrisiterative(Tnode *root) {
Tnode *current = root, *pred = NULL, *succesor = NULL;
while (current != NULL) {
succesor = current->right;
if (succesor != NULL && current->next==NULL) {
while (succesor->left != NULL) {
succesor = succesor->left;
}
current->next = succesor;
}
if (current->left == NULL) {
printf(" %d ", current->data);
current = current->right;
} else {
pred = current->left;
while (pred->right != NULL && pred->right != current) {
pred = pred->right;
}
if (pred->right == NULL) {
pred->next = current;
pred->right = current;
current = current->left;
} else {
pred->right = NULL;
printf(" %d ", current->data);
current = current->right;
}
}
}}
