HackerRank Matching Anything But a Newline Solution

dot

The dot (.) matches anything (except for a newline).

Note: If you want to match (.) in the test string, you need to escape the dot by using a slash \..
In Java, use \\. instead of \..

Regular expressions are extremely useful in extracting information from text such as: code, log files, spreadsheets, documents, etc.

We can match a specific string X in a test string S by making our regex pattern X. This is one of the simplest patterns. However, in the coming challenges, we‘ll see how well we can match more complex patterns and learn about their syntax.

Task

You have a test string S.
Your task is to write a regular expression that matches only and exactly strings of form: abc.def.ghi.jkx, where each variable a, b, c, d, e, f, g, h, i, j, k, x can be any single character except the newline.

Note

This is a regex only challenge. You are not required to write any code.
