建一个二叉搜索树,然后前序输出. 用链表建的,发现很久没做都快忘了... #include <cstdio> #include <cstdlib> struct Node{ int v; Node* l; Node* r; }; Node* root; Node* newnd(int value) { Node* u = (Node*) malloc(sizeof(Node)); if (u != NULL) { u -> v = value; u -> r = u -…
Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. No…
