iven an input string (s) and a pattern (p), implement wildcard pattern matching with support for '?' and '*' where: '?' Matches any single character. '*' Matches any sequence of characters (including the empty sequence). The matching should cover the entire input string (not partial).

Write a regular expression, usable with Python's re.search, which captures in its capture groups the parts of a rudamentary URL as defined below: Examples of URLs: http://bing.com https://google.com https://yahoo.com https://www.ycombinator.com/ The pattern should capture: The scheme (the "https://" part) The domain (the part after the scheme and before the top level domain (TLD), e.g. "bing" or "www.ycombinator") The top level domain (aka. TLD) (the last part, eg. "edu", "com", "gov") You do not need to handle URLs with paths (such as http://google.com/foo/bar), unless the path is just / as above, nor do you need to handle URLs with query strings (such as https://example.com?foo=bar). For the last example: >>> re.search(pattern, 'https://www.ycombinator.com/').groups() ('https://', 'www.ycombinator', 'com') Assign your pattern to a variable named pattern.
