Алгоритмы и структуры данных

Эта коллекция алгоритмов и структур данных и Вопросов со интервью c ответами. Этот репозиторий состоит с моих решений для алгоритмических задач и реализации структур данных на языке Java. Я создал этот репозиторий для изучения алгоритмов. И буду заполнять ее решениями постоянно.

На данный момент уже выложено решения более 300 алгоритмических проблем, так-же реализация популярных алгоритмов и структур данных
