I had recently asked a question on Stack Overflow and a few people had edited my question which was distorting the information provided by me. How can I restrict a post to be edited by others?
Q. How can I restrict a post to be edited by others?
Also, if you feel that a lot of other users are editing your posts inappropriately, then you can raise a custom flag on that post to a moderator, explain the moderator very clearly what is going on, and if the moderators thinks that there is some wrong editing going on, they can lock your post, so that no more edits would be allowed to it.
Q. a few people had edited my question which was distorting the information provided by me.
I feel that in your case, I'm guessing you're referring this question, the edits were made just to make your post a bit more readable. Agreed that they weren't great edits, but none of it seemed to distort the information provided by you.
The thing with the backslashes is that the very first version of your question itself had the backslashes. They just brought it to the limelight while formatting the question. Click on the source link on the first version in the history of that question and you can see the question as a raw text. It already had the backslashes.
Stack Exchange is a network of Collaboratively Edited sites.
On the about page it says:
Our goal is to have the best answers to every question, so if you see questions or answers that can be improved, you can edit them.
Use edits to fix mistakes, improve formatting, or clarify the meaning of a post.

All contributions are licensed under Creative Commons, and this site is collaboratively edited, like Wikipedia. If you see something that needs improvement, click edit!
Editing is important for keeping questions and answers clear, relevant, and up-to-date. If you are not comfortable with the idea of your contributions being collaboratively edited by other trusted users, this may not be the site for you.
Note: Editing code is a bit different and has slightly different rules, but is still encouraged
The short answer is: you can't. What you can do, however, is roll back the question revision.
