https://leetcode.com/problems/convert-sorted-list-to-binary-search-tree/ 题目: Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. 思路: 简单起见,先把链表值存到数组中,用数组递归感觉会简单点。。 算法: public int getListLength(ListNod...
To compute the height of a tree, start at its leaf nodes and assign them a height of 0. Then move up the tree using the three rules outlined to compute the height of each leaf nodes' parent. Continue in this manner until every node of the tree has been labeled. The height of the ...

A gas-efficient Solidity library using the iterative (rather than recursive) Red-Black binary search tree algorithm to help you maintain a sorted uint key index for your data. Insertions, deletions and searches are in O(log n) time (and ~gas). Note that the key of 0 is prohibited. Use...
