In computer science, the string-to-string correction problem refers to determining the minimum cost sequence of edit operations necessary to change one string into another (i.e., computing the shortest edit distance). Each type of edit operation has its own cost value. [1]
In physics, the Polyakov action is an action of the two-dimensional conformal field theory describing the worldsheet of a string in string theory.It was introduced by Stanley Deser and Bruno Zumino and independently by L. Brink, P. Di Vecchia and P. S. Howe in 1976, [1] [2] and has become associated with Alexander Polyakov after he made use of it in quantizing the string in 1981. [3]
String theory is a theoretical framework that attempts to address these questions. The starting point for string theory is the idea that the point-like particles of particle physics can also be modeled as one-dimensional objects called strings. String theory describes how strings propagate through space and interact with each other.
The right quotient of a character a from a string s is the truncation of the character a in the string s, from the right hand side. It is denoted as s / a {\displaystyle s/a} . If the string does not have a on the right hand side, the result is the empty string.
Considering mathematics as a formal language, a variable is a symbol from an alphabet, usually a letter like x, y, and z, which denotes a range of possible values. [7] If a variable is free in a given expression or formula, then it can be replaced with any of the values in its range. [8] Certain kinds of bound variables can be substituted too.

A string is defined as a contiguous sequence of code units terminated by the first zero code unit (often called the NUL code unit). [1] This means a string cannot contain the zero code unit, as the first one seen marks the end of the string. The length of a string is the number of code units before the zero code unit. [1]
A non-continuation byte (or the string ending) before the end of a character; An overlong encoding (0xE0 followed by less than 0xA0, or 0xF0 followed by less than 0x90) A 4-byte sequence that decodes to a value greater than U+10FFFF (0xF4 followed by 0x90 or greater) Many of the first UTF-8 decoders would decode these, ignoring incorrect bits.
