总共有三种顺序:in-order, pre-order, post-order. Take a look at this link:https://www.geeksforgeeks.org/tree-traversals-inorder-preorder-and-postorder/ 先序遍历(pre-order) 先访问根节点,然后访问左节点,最后访问右节点(根->左->右) 中序遍历(in-order) 先访问左节点,然后访问根节点,最后访问...

The optimal cost for freq[i..j] can be recursively calculated using following formula. We need to calculateoptCost(0, n-1)to find the result. The idea of above formula is simple, we one by one try all nodes as root (r varies from i to j in second term). When we makerthnode as...
We use trees in various areas of computer science, including operating systems, graphics, database systems, and computer networking. They are advantageous for data storage and retrieval.
