Title: http://hzwer.com/3419.htmlTest instructions: Give you a series of all 0, there are m operations [Li,ri], each operation will be subscript in [Li,ri] element inverse. You can choose a number of actions to make the series look different at the end of the sequence.Analysis:It is easy to know that if each operation is not replaced by a combination of other operations, then this operation will contribute to the set of operations, it is possible to have X such an operation, since the ans= opera

Ansible Introduction
Ansible is a new automated operation tools, based on Python development, the collection of a number of operations tools (puppet, Cfengine, Chef, func, fabric) The advantages of the implementation of batch system configuration, batch program deployment, batch Run command and other functions.

The lineinfile module is similar to the sed tool in linux, but the articles on the Internet generally only have simple instances, and there are no examples of complicated points.
The following is a common example of the lineinfile Module I have summarized based on my actual operations.
