An alternative that best describes the language represented by the following regular expression is (A) strings do not have 2 consecutive 0s.
<h3>
What is a regular expression?</h3>
- A regular expression (abbreviated regex or regexp; sometimes known as a rational expression) is a string of letters that indicates a search pattern in the text.
- String-searching algorithms typically use such patterns for "find" or "find and replace" operations on strings, as well as input validation.
- In theoretical computer science and formal language theory, regular expression techniques are developed.
- As an example: Strings do not have two consecutive 0s, which is an alternative that best describes the language represented by the following regular expression (0∪ε)(1∪10).
Therefore, an alternative that best describes the language represented by the following regular expression is (A) strings do not have 2 consecutive 0s.
