Problem Description
There are roughly 6,500 spoken languages in the world today. However, about 2,000 of those languages have fewer than 1,000 speakers. The most popular language in the world is Mandarin Chinese. There are 1,213,000,000 people in the world that speak that language.
Your task in this problem is to make a program to find out some syntax statistics of the languages that are written in English alphabet. The statistic is about the length of the words in the languages. Your program should read a text and display the length of the shortest and longest words, how many times the least and most frequently lengths occur, and the average word length in the text.
Input
The input is a text file that contains, English letters, and four punctuation marks: ‘.’, ‘,’, ‘?’, and ‘!’. The words are separated with one or more spaces. There is no space between a word and the following punctuation mark.
The longest word in the text can contain at most 99 letters.
Output
The output file has five lines displaying the shortest length, the longest length, the average length which is rounded to the nearest tens, the most frequently length and the least frequently length. In the case there
are two or more least or most frequently lengths, display the shortest one.
Example
