binary options algorithm

1. Sequential LookupIn the lookup we iterate through all the keys in the table in one order and use the Equals () method to find the matching key.Advantages: The structure of an array has no specific requirements, it can be implemented using arrays or linked lists, and the algorithm is simple.Disadvantage: When the number of arrays n is large, inefficient.Time complexity: When looking for a hit, the maximum time complexity is O (n), the minimum time c

title : How to judge a binary tree is a balanced binary treedefinition :Balanced binary tree (AVL): 1, empty binary tree is AVL tree;2, if T is a non-empty two-fork search tree, TL and TR respectively is its Saozi right subtree, then when T satisfies the condition, T is an AVL tree: (1) TL and TR are AVL trees; (2) | H

This algorithm is not difficult, and there are a number of algorithms for the implementation of today, see a Baidu said that they realized a bit, for reference Think: decimal number Num,num% 2 The resulting number is stored in the array list, and num = num/2 until num = 0, the resulting array of reverse output is the binary number we want to get Program: public static String to_binary (int orain) { lis

Binary lookup, also known as binary search (binary search), requires an array of ordered (sort), by comparing the intermediate data of the array (center-biased method) to determine the scope of the lookup value; Until the median value equals the lookup value, the lookup succeeds; If unsuccessful, reset the data, judge the size of the beginning and end position,

Defined:Tree:A tree is a finite set t of N (n≥0) nodes, and when n>0 meets the following conditions:(1) There is only one specific node called root (Root);(2) When n>1, the remaining nodes can be divided into m (m>0) disjoint finite set T1, T2 、...、 Tm, each set Ti (1≤i≤m) is a tree, and is called the subtree of the tree T (subtree).In particular, a tree that does not contain any nodes (that is, n=0) is called an empty tree.Here is the structure of a tree: Ordered tree: If the subtree of e

odd-even segmented arrays Splits an array of integers so that the odd number is behind the first even number. Sample Example Given [1, 2, 3, 4], return [1, 3, 2, 4]. algorithm This problem is still relatively simple, the method is many, we will loop through the array, the traversal of the number of even and odd exchanges between the OK. public class Solution { /* * @param nums:an array of integers * @return: Nothing */public void parti Tionarra
