Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, specifically in topology, the operation of connected sum is a geometric modification on manifolds. Its effect is to join two given manifolds together near a chosen point on each. This construction plays a key role in the classification of closed surfaces. More generally, one can also join manifolds together along identical submanifolds; this generalization is often called the fiber sum. There is also a closely related notion of a connected sum on knots, called the knot sum or composition of knots.

Второе издание одной из самых авторитетных книг по программированию посвящено использованию структур данных и алгоритмов. Алгоритмы — это основа программирования, определяющая, каким образом разрабатываемое программное обеспечение будет использовать структуры данных. На четких и простых программных примерах автор объясняет эту сложную тему, предлагая читателям написать собственные программы и...
