Look inside

Play the role of chief guest engagement officer at an amusement park. You’ve decided to model the visitor experience by using a queue data structure to simulate guests waiting in line for a ride. The park’s sales and marketing department would also like you to study what might happen if VIP (very important pocketbook!) visitors are allowed to jump to the front of various park attraction lines using a special pass. As you carry out these tasks, you’ll experiment with different types of queues, write a function to detect loops in a linked list, build a queue using a doubly linked list, and create trees, fundamental data structures in many algorithms. When you’re done, you’ll have the experience and skills you need to build a complete waiting-customer model and other programs using linked data structures in Go.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

Rod Stephens

Rod Stephens started out as a mathematician but discovered the fun of algorithms and has been programming ever since. Rod was a Microsoft Visual Basic Most Valuable Professional (MVP) for 15 years, has spoken to user groups and conferences, and has taught introductory programming courses. He has written more than 35 books including Essential Algorithms: A Practical Approach to Computer Algorithms Using Python and C# and Beginning Software Engineering, both of which include material related to this series of liveProjects.


This liveProject is for Go programmers, from beginning level to advanced, who want to learn how to create models in Go using linked data structures. To begin these liveProjects you’ll need to be familiar with the following:


  • A Go compiler (such as Visual Studio Code or Online GDB)
  • Basic math
  • Basic Go features (including structs and slices)


You choose the schedule and decide how much time to invest as you build your project.
