Data Structures and Algorithms in Go 🚀

Welcome to Data Structures and Algorithms in Go! 🎉 This project is designed as a dynamic, hands-on resource for learning and practicing data structures and algorithms in the Go programming language.

• More than one hundred rehearsal problems, at least six problems for each of the fifteen topics
• Executable and comes with 100% test coverage, ensuring correctness and quality
• Completely free, community-editable, and continuously evolving
• Ability to study and practice in your favorite IDE, editor, or web browser
