string technique

String techniques involve manipulating sequences of characters—called strings—using various programming methods. These techniques include operations like concatenation (joining strings), slicing (extracting parts), searching for substrings, replacing content, and formatting. They are fundamental for processing textual data, enabling tasks such as validating input, parsing data, and creating dynamic output. Think of strings as sequences of symbols or words, and string techniques as the tools that allow you to efficiently work with and modify that text within a programming environment.
