Remove extra spaces after the end of the string

Writing functions:

rtrim(x)

Remove extra spaces and tabs (after the end of the string) otherwise, it returns the default value (if the value is not a string).

The function of removing unnecessary spaces and tabs at the end of a line is one of the important tasks of a programmer. In the process of software development, there are often situations when data that includes strings contains additional characters, such as spaces or tabs, at the end of each line.

Such extra characters can lead to undesirable results or errors in the program. Therefore, to avoid such problems, it makes sense to create a function that will process strings and remove any spaces and tabs at the end of the line.

A software function designed to implement this task can be written as follows:

rtrim

This example uses the rtrim() function, which is built into most programming languages and removes all spaces and tabs at the end of a line. The returned value is a processed string without extra characters.

It is important to note that this implementation of the function removes characters only at the end of the line, without affecting spaces and tabs inside the line. If you need to remove spaces and tabs from all positions in a line, then you should use another method, such as replace() or regular expressions, depending on the programming language.

Thus, the rtrim() function is a simple and effective solution for removing unnecessary spaces and tabs at the end of a line, which can be used in various programming scenarios.
