Let’s look at the renderings first.The font icon used before the red dot is a right sign. Here, for convenience, the circle is used instead of the selected state, so it is not very good-looking. It needs to be modified by itself.）
I directly use vue-cli to build the project, the code directory is as follows:
The way of use is as follows:
treeDataThe format is as follows:
treeData: [

Explain:
This article mainly uses Python to achieve common sorting and search algorithms:Bubble sort、Selection sorting、Insertion sort、Shell Sort、Fast sorting、Merging sortingas well asTwo point lookupWait.
The basic idea of the algorithm is briefly explained, so long as the basic idea is understood, it has nothing to do with language realization.
This article mainly refers to the internet article, for learning only.
Development environment: Python3.5
Bubble sort
Bubble Sort is a relatively common sorting algorithm. It iterates over the sequence...
Cursor
Cursors are used to process multiple rows of records retrieved from the database (using SELECT statements). Using cursors, programs can process and traverse the entire recordset returned once retrieved one by one.
To process the SQL statement, Oracle will allocate a region in memory, which is the context area. This section contains the number of processed rows, pointers to the analyzed statement, and the entire section is the data row set returned by the query statement. The cursor refers to the handle or pointer of the context area.
Two. Classification of cursors:

DataGridWhen Binding datatable,
Datagrid.Itemsource=dt.DefaultView；
DataGRID will find many lines.
Solution 1 is as follows:
The operation of CanUserAddRows attribute of Datagrid is OK.
<DataGrid CanUserAddRows="False"../>
takeCanUserAddRowsAssignmentFalse，Otherwise, an extra row will be generated automatically, even thoughItemSourceBoundListAcountIt’s 0. Set to false can avoid this problem.True，Cooperate with each otherDataGridCheckBoxColumnIt’s even more strange. If the checkbox on the last line is checked, then clicking on any of the other lines will generate an e...

Template mode, as the name implies, is through the way of template rubbing.
Defining templates is defining frameworks, structures, and prototypes. Define an agreement that we always abide by.
Defining the template, our remaining work is to enrich it, enrich it, and improve its shortcomings.
Definition templates are defined by abstract classes. Common structured logic needs to be completed in abstract classes. Only non-public partial logic is abstracted into abstract methods, leaving the subclasses to enrich the implementation.
So the shortcomings mentioned above are th...
