The book defines complexity as a numerical function T (n)-the relationship between time and input size n, as one of the basic ideas of computer science. The computational complexity is categorized by algorithm based on its nature and function. The (computational) complexity of the algorithm is a measurement of the ratio of computational resources (time and space) consumed when a particular algorithm is running. For these issues, the book tries to locate heuristic algorithms which can almost explain the problem and operate in a reasonable timeframe. Different kinds of algorithms are described such as graph and network algorithms, algebraic algorithms, parallel algorithms and randomized algorithms.

Leverage Swift to practice effective and efficient test-driven development (TDD) methodology. Software testing and TDD are evergreen programming concepts―yet Swift developers haven’t widely adopted them. What’s needed is a clear roadmap to learn and adopt TDD in the Swift world. Over the past years, Apple has invested in XCTest and Xcode’s testing infrastructure, making testing a new top priority in their ecosystem. Open-source libraries such as Quick and Nimble have also reached maturity. The tools are there. This book will show you how to wield them.

The mercurial villain Loki resumes his role as the God of Mischief in a new series that takes place after the events of “Avengers: Endgame.”

Siblings Mimi and Luke unwittingly resurrect an ancient alien overlord. Using a magical amulet, they force the monster to obey their childish whims, and accidentally attract a rogues' gallery of intergalactic assassins to small-town suburbia.

When the love of his life is kidnapped and held for ransom by terrorists, a war hero Brad Paxton races against the clock to rescue her in a daring and deadly operation that pits him against the most powerful and shadowy forces.

Working in the shadow of his father, an esteemed police veteran (Samuel L. Jackson), brash Detective Ezekiel "Zeke" Banks (Chris Rock) and his rookie partner (Max Minghella) take charge of a grisly investigation into murders that are eerily reminiscent of the city's gruesome past. Unwittingly entrapped in a deepening mystery, Zeke finds himself at the center of the killer's morbid game.
