Golang program to implement a Merkle tree
A merkle tree is used in cryptography and computer science to verify the authenticity of a data efficiently. Merkle trees are extremely crucial in the fields of cryptography and blockchain technology for ensuring data integrity and security. In this article, we will learn the significance of Merkle trees and to implement a merkle tree in go. Here we are going to use two different examples to perform this implementation in the first example we will build the Merkle tree recursively through the `MerkleNode` struct with hash, left, and right pointer, and in the second example we will employ an ...
Read MoreGolang program to implement a Bloom filter
Bloom filters are a space-efficient data structure that find widespread use in various applications involving membership testing. In this article, we are going to explore how to create a Bloom filter in golanguage. Here we are going to write two different examples for this implementation, the first example includes the use hash functions from the FNV-1a algorithm, and in the second example we are going to use a a []bool array in order to determine element presence efficiently. Explanation A Bloom filter can be described as a probabilistic data structure that checks for the existence of an element in a ...
Read MoreGolang program to find the cross product of two vectors
The cross product is an operation performed on two vectors in three-dimensional space that results in a third vector that is orthogonal (perpendicular) to the original vectors. In this article, we will see the Golang program to find the cross product of two vectors, here we will explore two different methods. Explanation Let us assume we have two vectors A and B. The cross product of the two vectors can be calculated by the formula: C = A X B. Components of a cross product vector can be calculated by formula: Cx =Ay ⋅Bz −Az ⋅By Cy ...
Read MoreGolang program to find the dot product of two vectors
The dot product is a measure of how closely two vectors are aligning in the direction that they are pointing towards. The dot product of two vectors is a fundamental operation in linear algebra that calculates the sum of the products of corresponding elements in two vectors. In this article, we will write a Golang program to find the dot product of two vectors using a loop as well as using the go languages range keyword. Explanation The dot product of two vector is calculated by the formula shown below: DOT PRODUCT = A⋅B =Ax ⋅Bx +Ay ⋅By +Az ...
Read MoreGolang Program to Convert String Value to Byte Value
In this tutorial, we will learn how to convert string values to byte values using golang programming language. String Value − A string value is just a sequence of characters, like "abc". A string value is always enclosed in quotes. All types of characters are allowed (even digits, as in "abc123"). Strings can contain any number of characters. Byte value − The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where ...
Read MoreGolang Program to Perform the Comb Sort Algorithm
Comb sort algorithm is a simple and efficient comparison−based sorting algorithm, Comb Sort improves upon Bubble Sort by eliminating small values towards the end of the array, resulting in faster sorting times. We can use two methods to implement Comb Sort algorithm in Gzolang, the first method is using a naive approach and the other one is using an optimized approach in which we enhance the efficiency of the algorithm by introducing a flag variable to track swaps. In this article, we will discuss the principle of comb sort algorithm and provide the syntax for the program. Explanation The Comb ...
Read MoreGolang Program to Iterate Map Elements using the Range
Maps in Golang provide a convenient way to store and access the given data in format of key−value pairs. Iterating over a map allows us to process each key−value pair and perform operations on them. In this article, we will explore different methods to iterate map elements using the range, that includes using the range keyword, using keys and values slices, and using the reflect package. Syntax for key, value := range mapName { // Perform operations on key-value pair } This syntax uses the range keyword to iterate over the elements of ...
Read MoreGolang Program to Create a Copy of the Map
Maps are reference data types in Golang, which means that assigning one map variable to another creates a reference to the same underlying data structure. To create an independent copy of a map, we need to use different methods. In this article, we will explore two methods that include the manual method and the copy() function method to create a copy of map in golanguage. Syntax newMap := make(map[keyType]valueType) In this syntax, we first declare a new map named newMap using the make() function, specifying the appropriate key and value types. originalMap := map[string]int The syntax originalMap ...
Read MoreGolang Program to Perform Slices Permutations of Numbers Entered by the User
A slice is a portion of data extracted from an array, list or a data structure. Permutations refer to the rearrangement of elements in a specific order.Here slice permutation means to generate all the possible permutations of the number entered by user. In this article, we will explore how to perform slices permutations of numbers entered by user in Golang, using two methods the recursive approach and the iterative approach, to generate all possible permutations of the given slice. Explanation Recursive: Our first trick is the generatePermutationsRecursive() function. It starts simple, handling small batches of numbers like a warm−up. ...
Read MoreGolang Program to Print a Matrix in Spiral Format
To Print a matrix in spiral format we need to traverse the matrix in a spiral pattern, starting from the outermost layer and gradually moving inward. This approach provides a visually appealing way to display matrix elements. In this article we will use two methods to print a matrix in spiral format, the first method is by using the iterative approach and the other one is using the recursive approach. The examples below will help you understand these methods. Explanation Let us assume we have a 3 x 3 matrix, to print a matrix in spiral format we need to ...
