SOP (Sum of Product) and POS (Product of Sum) are the methods of representing a reduced logic expression. The basic difference between the two is that SOP expresses a Boolean function as a sum (logical OR) of product (logic AND) terms, while POS expresses a logic function as a product (logic AND) of sum (logic OR) terms. Read this article to learn more about SOP and POS and how they are different from each other. What is SOP? Sum of Product (SOP) is a method of representing a logic function by using minterms. The expression of a SOP includes product ... Read More
One of the features of Go is the ability to search and retrieve files based on a specified pattern. In this article, we will discuss different methods to get the list of filenames that match a specified wildcard pattern in Go, and provide syntax and examples for each method. Method 1: Using the "filepath.glob" The "filepath.Glob" method is the easiest and most straightforward way to retrieve the list of filenames that match a specified wildcard pattern. The function takes a pattern as input and returns a slice of strings that match the pattern. Syntax filenames, err := filepath.Glob(pattern) The ... Read More
In Go, a directory is a special type of file that holds other files and directories. A directory is used to organize files on a file system and provides a structure to the file system. Go provides several functions in the os package to work with directories, including: os.mkdir, os.remove, os.open, etc. Syntax func Stat(name string) (fi FileInfo, err error) The Stat() function is present in os package and is used to check the status of a particular directory. The function takes a string parameter name, which represents the path of the directory. It returns a FileInfo structure, fi, ... Read More
Smoke testing and Sanity testing are two important types of testing in software development. Both the tests are used to validate the functionality of a software product and identify any critical issues, however they are quite different in their scope. The basic difference between the two is that smoke testing is one that ensures that the features of an application are working fine or not, whereas sanity testing is one that is performed to test whether all the errors have been fixed after the build of the application. Read this article to learn more about smoke testing and sanity ... Read More
In the Go programming language, a file is a named resource for storing data that can be read from or written to. It provides a way for the program to persist data, even after the program has finished executing. Here in this article we will discuss different methods using which we can count the number of lines in a file. Method 1: Using a user-defined function In this method, we will write a go language program to count the number of lines present in the file by using bufio, fmt and os packages. Algorithm Step 1 − First, ... Read More
In Go, postorder tree traversal is a technique in which the left child is visited first, then the right child, and finally the root node is the definition of the order. This order is frequently used to carry out certain activities on a tree, including releasing memory that the tree has consumed. We will implement postorder tree traversal using two methods the first one uses slices and the second one uses stacks. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first argument ... Read More
SIMM and DIMM are types of memory modules which are designed to eliminate the use of Dual Inline Package (DIP) chips because the installation of DIP chips is difficult. The basic difference between the two is that SIMM has only one side that is usable at a time because it has only one set of connector, whereas DIMM has different usable pins at each side. Read this article to learn more about SIMM and DIMM and how they are different from each other. What is SIMM? SIMM stands for Single In-Line Memory Module. SIMM is a type of memory module ...

In Go programming language, a tree is a data structure in which each node has a value and zero to many nodes as children. The root node is the node without a parent, while the leaf node is the node 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 count no. of leaf nodes in a tree. In the first method TreeNode struct is used whereas queue is used in the second example to execute the program. Method 1: Using TreeNode Struct This ... Read More
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 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
