Single and double threaded trees are types of binary trees that maintain additional information for traversing the tree without the need for recursion or stack.

1. Single Threaded Trees: In a single threaded binary tree, each node is threaded towards either the in-order predecessor or successor (left or right) means all right null pointers will point to the in-order successor OR all left null pointers will point to the in-order predecessor.

2. Double Threaded Trees: In a double threaded binary tree, each node is threaded towards both the in-order predecessor and successor (i.e., both left and right null pointers will point to some in-order predecessor or successor).

The main advantage of threaded binary trees is that we can traverse the nodes in any order with only the information available at the node itself. This makes threaded binary trees ideal for iterative tree traversals.
