does not affect the work of others.Other version control systems such as SVN have branch management, but after use you will find that these version control system creation and switching branches than the snail is still slow, it is unbearable, the results branch function became a device, we do not use.But git's branches are different, and git can do it in 1 seconds, whether it's creating, switching, or deleting branches! Whether your repository is 1 files or 10,000 files.Create and

Note: The merge sort referred to in this article refers to the two-way merge sort.Merge sort is a stable sorting algorithm with average, worst-case and best-case time complexity O (nlog2n). Recently, the recursive, non-recursive, and natural merge sorting algorithms of the merge sort were combed.The basis of the

Usage scenarios for merge sorting algorithmsThe merge sort algorithm and the fast sorting algorithm are the sort calculation used in java.util.Arrays. For the general basic data type, the Arrays.sort function uses a two-axis quick sort algorithm, whereas for object type

Create BranchRight-click on the/trunk/myproject directory, select "TortoiseSVN", then "Branch/tag ...", and in the "to URL" of the pop-up window, enter the address of the branch, where the target revision select Head revision , as shown, click OK to add log after the branch is established. This operation is very fast, the new branch in the repository is actually a revision to the trunk of a soft connection only, and did not really copy the file.5. Check out BranchRight-click the TE

In order to prevent the "wrong" on the road farther, now branch realize that it is time to synchronize with the trunk (merge trunk to branch).First, in the local trunk of the first update, there is conflict resolution conflict, ensure that the trunk and repository are fully synchronized, and then right-click on the/branches/myproject, select "TortoiseSVN", then "Merge ", in the popup window, s

Since the play ACM has been a sort of merger for a long time, now write a blog to introduce this algorithm:)The picture is from Wikipedia, showing the complete merge sort process. For example, the array {38, 27, 43, 3, 9, 82, 10}.In the introduction of algorithms, the chapter of Divide and conquer is referred to merge sort. First, the merge sort is a divide-and-c

There are 3 combinations of git strategies, one is Resovle, one is recursive, and the other is octopus. Where resolve and recursive apply to merging 2 Branch,octopus for merging 3 or more than 3 branch. For these 3 strategies, it is necessary to involve merge-base commit,ours commit and theirs commit, which is 3-way mege.3-way MergeAs shown, if you want to merge branch B into branch A, then branch A's tip c

The merge statement in SQL Server 2008 can do many things, and its function is to perform INSERT, update, or delete operations on the target table based on the source table. The most typical application is the synchronization of two tables.The following is a simple example of how the merge statement is used, assuming that there are two table product and productnew in the database, our task is to synchronize

Merge sort is the use of recursive and divide-and-conquer technology to divide the data series into smaller Antimeron tables, and then sort the sub-table, and finally use recursive steps to merge the ordered Antimeron table into an increasingly large ordered sequence, the merge sort consists of two steps, respectively:1) Divide sub-table 2)
