Mastering Go, Second Edition shows how to put Go to work on real production systems. For programmers who already know the Go language basics, this book provides examples, patterns, and clear explanations to help you deeply understand Go’s capabilities and apply them in your programming work. The book covers the nuances of Go, with in-depth guides on types and structures, packages, concurrency, network programming, compiler design, optimization, and more. Each chapter ends with exercises and resources to fully embed your new knowledge. This second edition includes a completely new chapter on machine learning in Go, guiding you from the foundation statistics techniques through simple regression and clustering to classification, neural networks, and anomaly detection.

  • Try to change the logic behind generatePassword.go by picking the password from a list of passwords found in a Go slice combined with the current system time or date.
  • Make the necessary changes to the code of queue.go in order to store floating-point numbers instead of integers.
  • Change the Go code of stack.go so that its nodes have three data fields of integer type, named Value, Number, and Seed. Apart from the apparent changes to the definition of the Nodestruct, what is the main change that you will need to make to the rest of the program?
  • Can you change the code in linkedList.go in order to keep the nodes of the linked list sorted?
  • Similarly, can you change the Go code of doublyLList.go in order to keep the nodes of the list sorted? Can you develop a function for deleting existing nodes?
  • Change the code of hashTableLookup.go so that you do not have duplicate values...
