SUBSTRINGS Meaning and
Definition
-
Substrings are sequential sequences of characters that can be derived from a larger string. In computing and language processing, a substring is a smaller portion of a string that is extracted or obtained by taking a consecutive group of characters from the original string. It is important to note that substrings must maintain the same order and adjacency as the original characters from which they are derived.
For example, consider the word "computer." The string "comp" or "puter" can be obtained from the original word, and they both qualify as substrings. However, "cmepo" does not constitute a substring because it does not maintain the same order and adjacent characters as the original word.
Substrings are commonly utilized in various computational tasks, such as searching, pattern matching, and text manipulation. They can be used to identify specific sequences within a larger string, perform operations on them, or gather relevant information for further analysis. Substrings can be of any length, ranging from a single character to the entire original string.
In summary, substrings are consecutive and ordered sequences of characters obtained by extracting a portion of a larger string. They play a vital role in many computational processes, enabling efficient manipulation and analysis of textual data.
Common Misspellings for SUBSTRINGS
Etymology of SUBSTRINGS
The word "substring" is a combination of two words: "sub" and "string".
The prefix "sub-" is derived from the Latin word "sub", meaning "under" or "below". In the context of "substring", it indicates that the substring is a portion or part of a larger string.
The word "string" primarily comes from Old English "streng", which eventually evolved into its current form. In its basic sense, a string refers to a sequence of characters or symbols. Consequently, in computer science and programming, a string represents a series of characters used to store and manipulate text.
Therefore, when combined, the term "substring" signifies a smaller string that is extracted or derived from a larger string.
