ATT, attribute Protocol, protocol for discovering, reading, and writing to-end devices (for BLE devices) 1 Introduction
ATT allows a device to provide a set of attributes with associated values as a serverLet the device as a client to discover, read, write these attributes, and the server can actively notify the client
The ATT defines two roles: server and Client

[Att $ = val]. If the end character of the attribute value represented by att is the character specified by val, this style is used for this element.
Assembly languages depend on the architecture. In Linux, the compiled assembly by GCC is an ATT syntax assembly by default. This article mainly introduces ATT Assembly: operand length, immediate number representation method, register reference, operand sequence, symbol constant, memory Reference.
1. The length of the operand
The length of the operand is expressed by the symbol after the instruction in B
immediate suffix are labeled "H" and "B" respectively, while at/T, hexadecimal immediately preceded by "0x", table 2.2 gives several corresponding examples.Table 2.2 The difference between Intel and the-t prefix

MOV eax,8
MOVL $8,%eax
MOV EBX,0FFFFH

int 80h
int $0x80
2. Direction of the operandIntel is in the opposite direction of the/t operand. In Intel syntax, t

There are three ways in which jquery offers usData ()Att ()Prop ()To set and get the properties of an object. But the design of these three methods does not repeat the useless design, then the three of their distinction is where it.Demo attr () Method: is the integration of the getattribute () and setattribute () methods in JSUsage is the most routine.$ (' div '). attr ({age:30,address: "Tianjin"});var = $ (' div '). attr ("Age");$ (' div ').

Given Preorder and inorder traversal of a tree, construct the binary tree.Note:Assume that duplicates does not exist in the tree.Problem solving idea One:Preorder[0] As root, dividing the Inorderleft, Preorderleft, Inorderright, preorderright four arrays respectively, and then Root.left=buildtree (Preorderleft,inorderleft); Root.right=buildtree (Preorderright,inorderright)The Java implementation is as follows:Public TreeNode Buildtree (int[]
Binary Tree Preorder Traversal:Given a binary tree, return the preorder traversal of its nodes ' values.For example:Given binary Tree {1,#,2,3} , 1 2 / 3Return [1,2,3] .Note:recursive solution is trivial, could do it iteratively?Recursive pre-order traversal is not used and can be implemented with the help of stacks. For a particular node, the sequence of pre-order traversal is: root, left, a
The problem:Given Preorder and inorder traversal of a tree, construct the binary tree.Note:Assume that duplicates does not exist in the tree.My Analysis:The idea behind this problem is really elegant and meaningful!We need to combinely use both preorder and inorder arrays.Rucursion:The first node in preorder[] must is the root of

Given An array of numbers, verify whether it is the correct preorder traversal sequence of a binary search tree.Assume each of the sequence is unique.Follow up:Could does it using only constant space complexity?Ideas:1. Divide and conquer, it needs NLG (N) time.2. Linear solutionKinda simulate the traversal, keeping a stack of nodes (just their values) of which we ' re still in the left subtree. If the next number is smaller than the last stack value,
