részkarakterlánc

A részkarakterlánc, a Hungarian term, translates to "substring" in English. It refers to a contiguous sequence of characters within a string. In computer science, understanding substrings is fundamental for various text manipulation operations. For example, when searching for a specific word within a larger document, you are essentially looking for a substring. The concept also applies to tasks like extracting parts of a URL, manipulating file names, or analyzing DNA sequences. Most programming languages provide built-in functions or methods to extract substrings from a given string. These operations typically require specifying a starting position and often an ending position or a length to define the desired portion of the original string. The substring itself can be of any length, from a single character to the entire original string. Working with substrings is a common building block for more complex string algorithms and data processing tasks.
