A set of these objects is generated by the Kleene star operation.
The number of changes needed to convert from one of these objects to another one is measured by the Levenshtein distance. A set of these objects is generated by the Kleene star operation. These objects are the inputs to the Knuth-Morris-Pratt and Rabin-Karp algorithms. P-examples of these variables are length prefixed, while C-style examples of these variables are (*) null-terminated. Two of them can be joined into one via concatenation. In C these variables are enclosed in double quotes during declaration. In Linux, these variables can be searched using the "grep" operation. For 10 points, name this data type consisting of a sequence of characters, which is often used to store text.
