FAQ
What is REGEX (Regular Expressions)?
A regular expression is a sequence of characters that define a search pattern. It is usually used by algorithms for "find and replace" operations as well as string validation. Example: a regular expression can validate if your user's input is actually what you expect (e.g., a mail address)
In what programming languages are your REGEX's working?
This could be Python, Java, JavaScript, C#, PHP, Perl, Ruby, Go lang, or any other language with REGEX support. Regular Expressions work slightly differently in each of these languages. Please specify your programming language when ordering so I can build your REGEX to work in that environment.
Do I have to upload a testing text with my order?
No, but it is advisable to do so. With your testing material, I can better verify my work.
