ESTIMATED TIME TO COMPLETE: 18 minutes We can use the idea of bisection search to determine if a character is in a string, so long as the string is sorted in alphabetical order. First, test the middle character of a string against the character you'r…

Assume s is a string of lower case characters. Write a program that prints the longest substring of s in which the letters occur in alphabetical order. For example, if s = 'azcbobobegghakl', then your program should print Longest substring in alphabe…
