+Once upon a time in a quaint village nestled between rolling hills and meandering streams, there lived a remarkable cat named Whiskers. Whiskers was no ordinary feline; he was a cat with a penchant for adventure and a flair for fashion. His most prized possession was a pair of sleek, knee-high leather boots that made him the talk of the town.
+
+Whiskers' boots weren't just for show—they were his ticket to exploring the world beyond the cozy village. One day, a call for help echoed through the cobbled streets. The villagers were in distress, plagued by a mischievous band of mice that had taken residence in their barns and pantries.
+
+Our daring cat, armed with his trusty boots and a heart full of courage, stepped forward to offer his services. The villagers were skeptical at first. After all, Whiskers was just a cat. But when he donned his iconic boots, an air of determination surrounded him, and doubts quickly transformed into hope.
+
+With each step, Whiskers displayed an uncanny agility, darting through the fields and alleys in pursuit of the elusive mice. His boots, crafted by a skilled cobbler with a flair for the dramatic, not only protected his paws but also added a touch of sophistication to his every move.
+
+The mischievous mice, unaware of the formidable opponent they were facing, soon found themselves outmatched by Whiskers' cunning strategy and lightning-quick reflexes. The villagers watched in awe as their unlikely hero in boots triumphed over the rodent invaders.
+
+News of Whiskers' heroic deeds spread far and wide, reaching even the neighboring kingdoms. Soon, he became a legend—a cat in boots whose bravery knew no bounds. Whiskers, however, remained humble, always returning to his cozy village and the adoring villagers who had once doubted him.
+
+As time passed, Whiskers continued to embark on daring adventures, his boots becoming a symbol of courage and resilience. The cat in boots became a beloved figure, not just in his village but across the entire realm.
+
+And so, in the heart of that quaint village, Whiskers the cat in boots lived out his days, a living testament to the extraordinary things that can happen when courage and style come together in perfect harmony.

+Общее задание:
+Выбрать художественный текст (четные варианты – русскоязычный, нечетные – англоязычный) и обучить на нем рекуррентную нейронную сеть
+для решения задачи генерации. Подобрать архитектуру и параметры так,чтобы приблизиться к максимально осмысленному результату. Далее
+разбиться на пары четный-нечетный вариант, обменяться разработанными сетями и проверить, как архитектура товарища справляется с вашим текстом. В завершении подобрать компромиссную архитектуру, справляющуюся достаточно хорошо с обоими видами текстов. 
+
+Задание по вариантам:
+нечетные вариант, художественный англоязычный текст
+
+Чтобы Запустить приложение нужно запустить файл app.py
+
+Технологии:
+
+Python
+TensorFlow (библиотека для машинного обучения)
+Keras (интерфейс высокого уровня для построения нейронных сетей)
+Описание работы программы:
+
+Загружает художественный текст из текстового файла.
+Проводит предобработку текста, создавая последовательности символов для обучения модели.
+Строит рекуррентную нейронную сеть с использованием LSTM (долгой краткосрочной памяти).
+Обучает модель на предоставленных данных.
+Генерирует новый текст, начиная с случайной подстроки обучающего текста.
+Входные данные:
+
+Текстовый файл с художественным текстом (путь к файлу задается переменной file_path).
+Выходные данные:
+
+Сгенерированный текст на основе обученной модели.
