Can you solve this real interview question? Construct Binary Tree from Inorder and Postorder Traversal - Given two integer arrays inorder and postorder where inorder is the inorder traversal of a binary tree and postorder is the postorder traversal of th
Given inorder and postorder traversal of a tree, construct the binary tree. 根据树的中序(左根右)和后序遍历(左右根)构造一棵二叉树· 后序遍历最后一个元素是根节点,通过根节点将中序遍历数组分为两个数组,分别是左子树和右子树节点的集合,在进行递归调用 ...
search(t->l); elseif((temp->value<t->value)&&(t->l==NULL)) t->l=temp; } /* to display inorder of tree */ voidinorder(N*t) { if(t->l!=NULL) inorder(t->l); printf("%d->",t->value); if(t->r!=NULL) inorder(t->r); ...

In this article, we are going to see how we can create aheight-balancedbinary Search tree from a given sorted linked list. Pay attention to the word "height-balanced" as it plays a huge role. We can create a binary search tree with the list by just creating a skew tree, where...
