This article discusses how to use queue to make non-recursion algorithm of binary link tree. As for a general binary tree, if we adopt sequence storage, firstly we should extend it first into a complete binary tree, secondly we store it to a temporary queue according to the sequence of up-down and left-right. On the basis of the properties of the complete binary tree and the queue, if we can confirm every element in the queue, then we can find the left and right children of the element in the queue. When we recur these steps, we can create a binary link bit tree. This algorithm enriches the method from recursion to non-recursion.
