Given a string str, find the length of the longest substring without repeating characters.  (a).For “ABDEFGABEF”, the longest substring are “BDEFGA” and “DEFGAB”, with length 6.

It’s important to note that none of .rstrip(), .lstrip(), or .strip() removes whitespace from the middle of the string. In each of the previous examples, the space between "Jean-Luc" and "Picard" is preserved.

Given a string, check whether it is a panagram or not.A panagram is a sentence that uses every letter at least once.The most famous example is: "he quick brown fox jumps over the lazy dog.Note:A panagram in one language isn't necessarily a panagram in another. Thismodule assumes the english language. Hence, the Finnish panagram'Törkylempijävongahdus' won't pass for a panagram despite being considereda perfect panagram in its language. However, the Swedish panagram'Yxmördaren Julia Blomqvist på fäktning i Schweiz' will pass despiteincluding letters not used in the english alphabet. This is because theSwedish alphabet only extends the Latin one.""" from string import ascii_lowercase def panagram(string):    """    Returns whether the input string is an English panagram or not.        Parameters:            string (str): A sentence in the form of a string.        Returns:.
