prefixstring
A prefix string is a fundamental concept in computer science and string manipulation. It refers to a string that forms the beginning portion of another, longer string. For example, if the string is "programming", then "pro", "prog", and "program" are all prefix strings of "programming". The empty string, "", is considered a prefix of every string, including itself.
Prefix strings are crucial in various algorithms and data structures. In string searching algorithms like Knuth-Morris-Pratt
When comparing two strings, determining if one is a prefix of the other is a common operation.
