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.

Which option correctly matches a string that starts with 'a' and ends with 'z', with any number of characters in between?^a*z$a*z^a.*z$a.+z

Problem Description: Nathan wants to implement wildcard pattern matching supporting only the wildcard '?'. The wildcard character '?' can be substituted by any single lower case English letter for matching. He has two strings X and Y of equal length, made up of lower case letters and the character '?'. He wants to know whether the strings X and Y can be matched or not. Constraints: 1 ≤ I ≤ 50 Both X and Y have equal length and the length is between 1 and 10. Both X and Y consist of lower case letters and the character '?'. Input Format: The first line of input contain an integer 'T' denoting the number of test cases. Each test case consists of two lines, the first line contains the string 'X' and the second contains the string 'Y'. Output Format: Print the output a single line with the word 'Yes' if the strings can be matched, otherwise output 'No'.
