#### Overview of this book

Golang is one of the fastest growing programming languages in the software industry. Its speed, simplicity, and reliability make it the perfect choice for building robust applications. This brings the need to have a solid foundation in data structures and algorithms with Go so as to build scalable applications. Complete with hands-on tutorials, this book will guide you in using the best data structures and algorithms for problem solving. The book begins with an introduction to Go data structures and algorithms. You'll learn how to store data using linked lists, arrays, stacks, and queues. Moving ahead, you'll discover how to implement sorting and searching algorithms, followed by binary search trees. This book will also help you improve the performance of your applications by stringing data types and implementing hash structures in algorithm design. Finally, you'll be able to apply traditional data structures to solve real-world problems. By the end of the book, you'll have become adept at implementing classic data structures and algorithms in Go, propelling you to become a confident Go programmer.

# Recursion

Recursion is an algorithm in which one of the steps invokes the currently running method or function. This algorithm acquires the outcome for the input by applying basic tasks and then returns the value. This method was briefly discussed in the Divide and conquer algorithms section of Chapter 1, Data Structures and Algorithms. During recursion, if the base condition is not reached, then a stack overflow condition may arise.

A recursion algorithm is implemented in the following code snippet. The Factor method takes the num as a parameter and returns the factorial of num. The method uses recursion to calculate the factorial of the number:

`//main package has examples shown// in Go Data Structures and algorithms bookpackage main// importing fmt and bytes packageimport (  "fmt")//factorial methodfunc Factor(num int) int {  if num <= 1 {    return 1  }  return...`
