Assume is s a string of lower case characters.Write A program This prints the longest substring of in s which the letters occur in alphabetical order. For example, if s = ‘azcbobobegghakl‘ , then your program should printLongest substring in alphabetical order Is:begghIn the case of ties, print the first substring. For example, if s = ‘abcbcd‘ , then your program should printLongest substring in alphabetical order IS:ABC# Paste Your code into this boxCount = 1result = SWhile S:Newcount = 1New

, which is still important even if you continue to use a more advanced widget collection.TK Brief Description TK is the most closely related to Tcl language, and widely used graphics library, Tcl language and TK are developed by John Ousterhout. Although TK appeared as a X11 library in 1991, it was actually ported to every popular GUI since then. (It is similar to the case where Python gradually has a "standard" GUI.) Now, most popular languages and

I want to introduce you to the simplest way to start GUI programming, using Scriptics's TK and Tkinter wrappers. We'll make a lot of comparisons with the curses library mentioned in "Curses programming in Python" in DeveloperWorks. In addition to the difference between curses implementing a text console and TK implemen
