Algorithms are step-by-step ways to solve problems. This book shows how to use them in code. It shows how tested methods can make programs run faster. These methods can make code simpler, too. Readers learn to use them for common coding tasks. They learn to compare how well the methods work.

The guide is for those learning about algorithms. It also suits those getting ready for coding interviews. It does not need high-level math. It starts with ways to sort and search. It then moves to harder tasks, such as data compression. It covers artificial intelligence, too. More than 400 playful drawings help explain the ideas. Dozens of examples help as well.

This second edition says more about trees and NP-complete problems. It also brings the code examples up to Python 3.
