AVL Tree is a highly balanced binary search tree.
1. Single rotation LL Rotation
Understanding memory:1. The imbalance caused by insertion of the left child on the unbalanced node is LL.

Excel table Formulas1. Formula for searching duplicate content: = If (countif (A: A, A2)> 1, "DUPLICATE ","").2. Calculate the age by Date of Birth: = trunc (days360 (h6, "2009/8/30", false)/360,0 ).
3. calculated from the input 18-digit ID card number's Birthdate: = concatenate (mid (E2,), "/", mid (E2 ),"/", mid (E2, 13, 2 )).
4. Ask the system to automatically extract gender from the entered ID card number. Enter the following formula:
= If (LEN (C2) = 15, if (mod (mid (C2, 15,1), 2) = 1, "ma
We often use Excel to process tables and data, in the process of processing tables and data, the use of formulas and functions, the following we have to organize some of the common Excel formulas and the use of methods, I hope to help you.
Find a duplicate content formula: =if (COUNTIF (A:AA2) >1 "Repeat" "").
Second, the date of birth to calculate the age formula: =trunc (DAYS360 (H6 "2009/8/30″false)"/3600).
Three, from the input of the 18-digit date of birth calculation formula: =concatena
Microsoft is the mainstream of modern enterprise information management systems, and the combination of. NET-based workflows and Microsoft's product architecture can maximize the value of IT investments. Workflow concept originates from the field of production organization and office automation, is a concept that has fixed program activities in daily work, and there are a variety of workflow systems at home and abroad, the industry standard is various, although the main function of workflow is m
enter the following formula:
=if (LEN (C2) =15,if (MOD) (MID (c2,15,1), 2 = 1, "Male", "female"), IF (MOD (MID (c2,17,1), 2) = 1, "Male", "female"), "C2" in the formula represents the cell that entered the ID number.
1, Sum: =sum (K2:K56)--to the K2 to K56 this area to sum;
2. Average: =average (k2:k56)-an average of K2
, integrate, and manage business-related data. To achieve this, the business department must work closely with IT experts to obtain the best solution-meeting business requirements and enhancing the performance of the process.
However, IT and business experts are always a challenge to accomplish this task. The developer will bake and remove the sac and drop it. The filter block is yellow, and the appearance is yellow, the yellow, the dust, the R drop, the yellow stop? It uses the UML (Unified

Compared with many new technologies, the visibility of the workflow may be smaller, but the workflow has been in constant innovation. What is different is that the application of new technology in this field is hidden under the application concept and the architecture system. For the development trend of workflow, here separate two lines to explain.
The first line is simply from the application of workflow technology development trend to explore. In this regard the international level of appli
meaning of SOA to enterprise users. For example, a service in SOA is not a traditional enterprise service that we understand, but a professional term in software development. It refers to functional modules at the technical level and with fine granularity, it is far from reaching the degree of direct correspondence with the Business Process of the enterprise. Software vendors have not explained this point while emphasizing that SOA brings great commercial value to enterprises.
