Question

What alternative best describe the language represented by the following regular expression? Group of answer choices Strings do not have 2 consecutive 0s. Strings that only start with 1. Strings do not have 2 consecutive 1s. Strings that consist of alternating 0s and 1s.

Answer 1

An alternative that best describes the language represented by the following regular expression is (A) strings do not have 2 consecutive 0s.

What is a regular expression?

• 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.
