Remove extra spaces

Writing functions:

trim(x)

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

The software function for removing unnecessary spaces and tabs at the beginning and end of a line is very useful when working with text data. It allows you to clear a string of unnecessary characters, which improves its visual representation and processing.

To use this function, you must pass a string to it as an argument. The function will look at each character of the string, starting from the beginning and up to the first non-whitespace character. Then it will go through the string in reverse order, starting from the end and up to the first non-whitespace character. All spaces and tabs at the beginning and end of the line will be deleted.

After applying the function, the line will be cleared of unnecessary spaces and tabs, which will simplify further data processing. This is especially useful when working with text files or when processing user input.

Thus, using a software function to remove unnecessary spaces and tabs at the beginning and end of a line will help you improve the quality of text processing and make your code cleaner and more readable.
