[C#] Домашно Strings and Text Processing - 8 задача Extract all sentences containing given word.

Extract Sentences.cs

using System;

/* Write a program that extracts from a given text all sentences containing given word.
 * Example: The word is "in". The text is: 
 * 
 * We are living in a yellow submarine. 
 * We don't have anything else. 
 * Inside the submarine is very tight. 
 * So we are drinking all the day. 
 * We will move out of it in 5 days.
 * 
 * The expected result is:
 * We are living in a yellow submarine.
 * We will move out of it in 5 days.  
 * 
 * Consider that the sentences are separated by "." and the words – by non-letter symbols. */
