There are generally two kinds of urlencode, one is the traditional based on GB2312 encode (Baidu, Yisou, etc.), the other is based on UTF-8 encode (Google, Yahoo and other uses).

branch. Use the GIT checkout name command to switch to the name branch. Git uses the head index to point to the current branch. For example, the master and next branches exist in the version. After the GIT checkout next command is used to switch to the next branch, the head points to next; use the GIT checkout master command to switch to the master branch, and the head points to the master. Iv. merge branches Common branch merge Commands include git merger, git rebase, and git cherry-pick. 1.

condition of the outer for loop termination is, I = a.length-1. Depending on the retention , the subarray is expanded to a[0~a.length-1], and is well-sequenced. So the algorithm is correct.3.

In this model, some commonly used computer instructions, including arithmetic instructions (add, subtract, multiply, divide, withdraw
