Golang program to compare two instances of this struct for equality, taking into account the values in the slice
A struct is a counterpart to class in object-oriented programming where different fields can be placed in the struct, where these fields can be implemented later on and they have a type like int, float, string etc.In this article, we will write a Go language program to compare the equality of two structs. Syntax func len(v Type) int The len() method returns the length of any parameter. It accepts one input, the data type variable whose length we want to know. func range(variable) The range function iterates through any data type. To utilize this, we must first put ...
Read MoreHow to find the capacity of the pointers pointing at a map in Golang?
A pointer is a variable which holds the address of another variable and can be used to point to the content of another variable. A pointer does not have its capacity just like slices, it can be used to point to the map whose length of elements can be calculated.In this article, we will write a Go language program to find the capacity of a pointer pointing to a map. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its ...
Read MoreGolang program to find the longest path in a weighted directed acyclic graph using Bellman-Ford algorithm
In this article, we will write a Go language program to find the longest path in a weighted directed acyclic graph using Bellman-ford-algorithm. Bellman-Ford-Algorithm is a popular algorithm used to find the longest path from source vertex to other vertices in a weighted directed graph. Syntax func range(variable) Any data type may be iterated over using the range function. This may be used by first writing the range keyword, then the data type to which we wish to iterate. func make ([] type, size, capacity) When creating an array or map in the Go programming language, the ...
Read MoreGolang program to find the minimum number of edges in a weighted directed graph that connects all nodes
In this article, we will write Go language programs to find the minimum no. of edges in a weighted directed graph that connects all nodes. We will use Prim’s algorithm to perform this operation. It is a greedy algorithm which is used to find the minimum spanning tree for a graph. Syntax func range(variable) Any data type may be iterated over using the range function. This may be used by first writing the range keyword, then the data type to which we wish to iterate func make ([] type, size, capacity) The go language's make function is used ...
Read MoreGolang program to perform a left rotation in a Red Black Tree
A red black tree is a self balancing binary search tree. Rotation is one of the fundamental operations of a self balancing tree. It is performed to maintain the tree's properties while inserting and deleting nodes to the tree. In this article we are going to write a language program to perform left rotation in a Red Black tree using pointers as well as using node value. Properties of Red Black tree Every node is either red or black The root node is always black Every leaf node is considered black If a node is red, both its children ...
Read MoreGolang program to find which Employees should get bonus
In corporate office there may be some cases in which you have a list of employees and you need to provide them extra bonus based on the work or experience or a particular property. In this article we are going to explore a way to calculate bonus using performance based calculations and tenure based calculations. Method 1: Performance Based Calculations Performance is the common base to determine the employee’s bonus, in this method we are going to calculate the bonus depending on the performance of the employee. Algorithm Create the Employee struct, which has the values Name, Salary, and ...
Read MoreGolang program to sort Employee by Name
There may be scenarios in which you need a list of employees and you need to display them in a particular order based on their name initials. In this Golang article, we are going to sort employee names using bubble sort, insertion sort as well as using go sort package. Algorithm Create a field called “Name” in the Employee struct. Use the array of Employee objects as input for the “BubbleSortByEmployeeName” method. Obtain the employees array's length and save it in the variable n. Start the outer loop from i = 0 to n-1 and Start the ...
Read MoreGolang program to takes a receiving channel of integers and a sending channel of strings
In this article, we will learn how to develop a golang program that takes a receiving channel as integer and sends a channel of strings. Here we will be using a concurrent approach that involves using the multiple goroutines to perform transformation concurrently as well as using select statements with timeout. Syntax channel_name := make(chan Type) To create a channel. channel_name
Read MoreGolang program to use a unidirectional channel to send integers from 1 to 10 to a receiving function
In this go language article we are going to use a unidirectional channel to send integers from 1 to 10 to a receiving channel. We will be using a basic channel, a buffered channel with fixed capacity as well as using a select statement for non-blocking channel operation. Syntax ch := make (chan int) To create an unbuffered channel Value :=
Read MoreHow do you create unidirectional channels in Golang?
When working with go language channels there must be cases such as clear communication intent, enhanced safety in communication, encapsulation and more where you need to create unidirectional channels. In this go language article we are going to learn to create unidirectional channels using send only channel method, receive only channel method, using interfaces as well as type conversion methods. Bidirection channels enables the channel data to be transferred and received. There may be times when you want to impose unidirectional communication, limiting either sending or receiving actions. Syntax ch := make(chan
