Preface:
Modern CPUs all have pipelines and branch prediction functions. The accuracy of CPU branch prediction can reach more than 98%. However, if the prediction fails, the pipeline fails and the performance loss is very serious.
For details about the branch prediction technology used by the CPU, refer:

In General, when merging branches, if possible, Git will use Fast forward mode, but when the branch is deleted, the branch information is discarded. If you want to force disable Fast forward mode, Git will be in Merge when you generate a new Commit , so that branching information can be seen from the branch history. let's do the actual combat --no-ff . Way of git

command can directly submit all the modifications, eliminating the need for git add, git diff, and git commit operations.
Note: you cannot add new files or folders. Therefore, if you add new files or folders, you must honestly Add. Git first, and then git commit.
Git log-P
If you think that the information provided by git log is too thin, you can use git log-P. In this way, git not only provides the development log, but also shows the code differences for each development version.

This article is still written for beginners, and the following is for all the branch structures and switch branches of if, and hopefully it will help beginners.
An If statement includes a single condition, a single branch, a single condition, a double branch, and a multiple-condition multiple branch.

The branch development in CVS is as follows:1. First create a trunk [the tag name ends with main]2. Create numerous branches on the trunk [branch at the end of the tag name], and then many people can develop based on this branch.3. When the branches reach a certain number, you can merge these branches and return them to the trunk. [in this case, merge is required
git reset [commit hash]However, this only allows the local branch to be rolled back to the commit, and the remote branch is in its original place.You can do this: create a new branch on the commit you want to roll back, then git checkout [the branch], then delete the original branc

First, the basic conceptSimilar to the backtracking method, it is also an algorithm for searching problem solution on the solution space tree T of the problem. However, under normal circumstances, the branch-bound method and the backtracking method are different in solving the target. The objective of backtracking is to find out all the solutions that satisfy the constraints in T, while the solution target of bran
generation of machine code is unlikely to be identical, can only hope that the difference is not large.

1. The remote branch is generated when the local branch is pushed to the server. For example, the master node is the most typical remote Branch (default ).

$: git push origin master
Apart from the master, we can also create branches and push them to the server. For example:
