maintain a 2-3-tree balance. For 4-node nodes, the height of the tree is not changed before and after the deformation of the 2-3 node. Only if the node is a 4-node node, the height of the tree is added one after the deformation. As shown in the following:AnalysisFor a fully balanced 2-3 lookup tree, the distance from each root node to the leaf node is the same:

of the outermost 4 (s-1) of the square with the size of SxS. Before you cut the grid paper, please calculate how many different boxes can be cut out altogether? Input The first line of the input file contains four integers h,w,l,p the total number of rows in the grid, the number of columns, the minimum limit for the length of the box, and the number of damaged squares. The next P line, where line I contains two integers x_i, y_i, indicates that the grid on the Y_i column of the x_i row

Java data structure and algorithm analysis (10)--2-3 Tree Binary lookup trees are efficient in most cases of finding and inserting, but they are less efficient in the worst cases. The data structure of the balanced lookup tree guarantees LGN efficiency in the worst-case scenario, and to achieve this we need to ensure that the tree remains in balance after the insert completes, which is the balanced lookup

10 debugging skills developed by Visual Studio (2): Visual Studio My previous articles on Visual Studio debugging skills have aroused great interest, so I decided to share more debugging knowledge. In the following list, you can see the Native Development debugging skills (followed by previous articles ). These skills can be applied to VS2005 or later versions (of course some of them can be applied to earli

At the invitation of a netizen, I wrote a numeric conversion function. If you have any shortcomings, click it. # Include /* * Function: int convert (INT num, char * STR, unsigned int Radix)* Function: convert a decimal integer to 2 ~ 36 (excluding 10) hexadecimal number* Parameter: num decimal integer* String buffer after STR conversion. Suppose the buffer is large enough.* Radix Base* Return value: 1

understand JavaScript. 1. Add an element at the end of an array. This technique allows you to use the Length attribute to add an element at the end of an array, because the Length attribute is 1 more than the subscript of the last element of the array. This method is the same as the "push" method. For example: CopyCode The Code is as follows: var myarray = []; Myarray [myarray. Length] = 'new element '; 2. Adjust the length of an array. The Leng

too many of the things, I am not here to gossip, But as a simple programmer who wants to do technology, I'm not comfortable with it. And whether it is leader or leader's leader, I do not want to accuse them, but it is obvious that they do not have appropriate control of this situation, but let it develop. How bad is the atmosphere? Let me give you some circumstantial evidence, less than 10 small teams. People, before I entered 1,
