http://fisherlei.blogspot.com/2013/01/leetcode-convert-sorted-list-to-binary.html View Code SOLUTION 3: 这个解法使用一个instance variable 来记录当前正在操作的List Node. DFS本身的效果是,从head直到尾部建树,并且将currNode移动到size+1处。 这样可以在1次iterator 我们的List后直接建立树。 这是一种Bo...
Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. Example: Given th...

Convert Sorted List to Binary Search Tree (如有侵权,请联系作者删除) Medium 题意 和上一题几乎一模一样,唯一的区别是上一题当中给定的是一个vector,而这题改成了链表。 深深地感受到了题目的恶意,比较容易想到我们完全可以手动把链表转化成vector完成转换的操作。我们并没有学到什么新的内容,也没有什么特别...
