The set of all strings that begin and end with either 0 or 1.c. The set of all strings containing at most two 0’s.d. The set of all strings containing the substring 00.

10. Regular Expression MatchingAttemptedHardTopicsCompaniesGiven an input string s and a pattern p, implement regular expression matching with support for '.' and '*' where:'.' Matches any single character.​​​​'*' Matches zero or more of the preceding element.The matching should cover the entire input string (not partial). Example 1:Input: s = "aa", p = "a"Output: falseExplanation: "a" does not match the entire string "aa".Example 2:Input: s = "aa", p = "a*"Output: trueExplanation: '*' means zero or more of the preceding element, 'a'. Therefore, by repeating 'a' once, it becomes "aa".Example 3:Input: s = "ab", p = ".*"Output: trueExplanation: ".*" means "zero or more (*) of any character (.)".

Which regular expression would match any string that contains 4 consecutive zeros?^0000[0-4]{0-4}0{4}

Given an input string s and a pattern p, implement regular expression matching with support for '.' and '*' where:'.' Matches any single character.​​​​'*' Matches zero or more of the preceding element.The matching should cover the entire input string (not partial). Example 1:Input: s = "aa", p = "a"Output: falseExplanation: "a" does not match the entire string "aa".Example 2:Input: s = "aa", p = "a*"Output: trueExplanation: '*' means zero or more of the preceding element, 'a'. Therefore, by repeating 'a' once, it becomes "aa".Example 3:Input: s = "ab", p = ".*"Output: trueExplanation: ".*" means "zero or more (*) of any character (.)". Constraints:1 <= s.length <= 201 <= p.length <= 20s contains only lowercase English letters.p contains only lowercase English letters, '.', and '*'.It is guaranteed for each appearance of the character '*', there will be a previous valid character to match.
