In Go programming language, pre-order traversal is a tree traversal technique in which the root node is visited first, then the left subtree, and finally the right subtree. A recursive function is used that calls itself on the root node, the left child node, the right child node, and finally the left child node again. When the node is nil, the recursion's basic case, occurs. We will execute pre-order traversal in this program using two methods- the TreeNode struct and the stacks. Method 1: Using TreeNode struct This method builds a tree node structure With a Value field, a pointer ... Read More

In the Go, a binary tree is a tree data structure where each node has at most two children, as the left child and the right child. Go's built-in data structures and operations, like structs and pointers, can be used to create a binary tree. The tree's nodes can be visualized as structs with fields for the value kept at each node and pointers to any left or right children. There are three types of tree traversals- preorder, inorder and postorder. We will use two methods to implement the binary tree data structure. In the first method we executed pre-order ...

In Golang data structures, a linked list is the one that contains nodes which contains two fields: a next pointer and the data of the list. We will use two methods to detect a loop in linked list. In the first method two-pointer approach will be used and in the second example maps are used to execute the program. Let’s go through those examples to understand the execution. Method 1: Using two-pointer approach In this method, the linked list is traversed using a low pointer and a high pointer. While the high pointer advances two steps at a time, the ... Read More

In golang data structures , a linked list has pointers connecting the items, and from the first node (head) to the last node, each node can be visited (tail) using next pointer. We will obtain the middle element of a linked list using two methods. The first approach depicts use of two-pointer approach and the second approach uses a counter variable to execute the program. Method 1: Using two-pointer approach In this method, the function navigates the linked list using two pointers, low and high. The high pointer takes two steps at a time, whereas the low pointer takes ... Read More

In Go programming language, a linked list is a linear data structure made up of a series of nodes which are linked to each other via next pointer, which points to the next address. We will implement linked list in this program using two methods. In the first method struct will be used and in the second example list struct will be used. Method 1: Using Struct In this method, there are three nodes in this linked list, and each one has a value of 1, 2, or 3. Each node's next pointer points to the node after it in ... Read More

In Golang, a dictionary is like a map which is a group of key-value pairs with a unique key for each value. The values can be of any type, and the keys can be of any type that is similar, such as strings or integers. We can build an empty map by using the built-in "make" function, and then add, retrieve, or update values. We will use two examples here to iterate through elements of a dictionary where in the first example loop will be used to iterate through the elements whereas in the next example slices will be used ...

In Golang, a collection is a data structure that stores a number of elements, usually of the same type. The collection types in Go offers arrays, slices, maps, and channels. Slices are considered as dynamic arrays whose size can be changed whereas arrays have a fixed size. Channels give goroutines a method to communicate and synchronize their execution, whereas maps are used for key-value storage. Here, we will show execution of maps, slices and arrays using different ways as shown below in examples. Method 1: Using map, slice and array This method shows how to use arrays, slices, and maps ...

In Go, a linked list is a linear data structure that contains a node which further contains two fields one is data and the other one is next. The next contains the address of the next node in continuation. We will execute this program with the help of two methods. In the first method linked list will be used a series of nodes and in the second example different variables are used to execute the program. Method 1 − Using linked list as series of nodes A linked list is described by this program as a collection of Nodes, each ... Read More

In Go programming language, a tree is a frequently used data structure that resembles an upside-down tree or an inverted tree with parent-child relationships between the nodes. In a tree, each node has a value and zero to many nodes as offspring. The root node is the node without a parent, while the leaves are the nodes without children. Trees can be employed for a variety of tasks, including data storage, sorting, and searching in hierarchical structures. We will use two methods to perform inorder tree traversal. Syntax func make ([] type, size, capacity) The make function in go ... Read More

In go we can use strings.Join to convert a arraylist into string. Here we will understand how we can use strings.Join to combine multiple texts from an array that are separated by commas and spaces also, strings. To create an array of strings, use the Split function on the string. Let’s see through the code and algorithm how its executed. Syntax func Join(s []string, sep string) string The join function is used to convert an array to string. This function is present in strings package. it takes two arguments first one is the array that we wish to convert ... Read More
