Write a program that gets one text with the maximum of 256 characters from input and converts it to standard format based on the following rules and prints the final standardized text:
 The only allowed characters in the text are: {‘a’..’z’}, {‘A’..’Z’}, {‘0’..’9’}, {‘?’,’!’, ’.’ }. Therefore you should delete not allowed characters.
 After each sentence just one space should be included.
 The first letter of each sentence should be capitalized.
 Having another capitalized character in the sentence except the first letter is not allowed.
 Having more than one space after each word is not allowed.
Note that in the entered text of the user the separator of words is the space and the ending of each sentence is ‘.’, as a result you could use these points for your text processing. You should give the detailed report about the text including following information:
 The number of characters
 The number of words
 The number of sentences
