Problem Description The problem is similar to Exercise2, but you need to sort words instead of numbers. Devise and implement an algorithm that sorts words in O(n) complexity, where n is the number of words in the input file (not counting the first word that has special meaning described below). The input file contains words separated by whitespaces. Each word consists of English letters a-z. There are 1, 2, or 3 letters in each word, the same letter can be used multiple times. The first word in the input file is so called maxword. It is some word that is equal to or greater than any other word in the file. Program Assume that you have n arbitrary words in range a..maxword. The words may be repeated. Sort them using the algorithm of O(n) complexity. Also sort them using any other algorithm of your choice. The program has to be case insensitive. For example, letters a and A has to be treated as equal. Sort all words from the file in alphabetical case insensitive order (for example, a precedes aa, ab, b, ba, and bb). Ignore the letters case and output words in small case only.
