In Git, local and remote repositories work together to manage and collaborate on code. A local repository is a copy of a Git repository that resides on your local machine and a remote repository is a copy of the Git repository hosted on a remote server or a cloud-based service (e.g., GitHub, GitLab, Bitbucket, or a private server). Pushing your local repository to a remote repository is a fundamental part of using Git, especially when working in a team or on a project that requires collaboration, backup, or version control. To push a local branch to a remote repository in ... Read More
Problem DescriptionIn this problem, we are given an array of integers, and our task is to calculate the absolute sum of its elements. The absolute sum means the sum of the absolute values of all the array elements. In this article, we are going to learn how to compute the absolute sum of an array's elements using C++.Example 1Input:arr = {-3, 2, -7, 4}Output:16Explanation:The absolute values of the array elements are:| -3 | = 3, | 2 | = 2, | -7 | = 7, | 4 | = 4The sum of these absolute values is: 3 + 2 + ...

In combinatorics, nCr and nPr are essential formulas used to calculate combinations and permutations. They represent the number of ways to select and arrange objects from a set. nCr refers to combinations, where order does not matter, while nPr refers to permutations, where order does matter. The permutation refers to the arrangement of objects in a specific order.A combination refers to the selection of objects without taking order in reference. In this article, we are going to learn how we can calculate nCr and nPr in Python using different approaches. The formula for nCr and nPr The formulas ... Read More
MySQL's ENUM data type is used to define a specific set of values in a column making it easier to manage and maintain data consistency. GROUP BY and WHERE() function In MySQL WHERE clause is used to filter the rows based on a condition before grouping them. The GROUP BY clause groups rows with identical values in specified columns, and can be used with functions like SUM, COUNT, and AVG. Together they enable focused data analysis by filtering and grouping efficiently. Syntax Following is the syntax to filter the data on certain conditions and to eliminate duplicate records. SELECT column1, ... Read More
Triggers in MySQL enable us to describe automatic operations that would be conducted as a result of specific actions happening within tables, such as INSERT, UPDATE, or DELETE. Triggers are very useful to automate repetitive database operations and maintain data integrity. Inserting a Row into Another Table with a Trigger Inserting a row into another table using trigger can be achieved by using the CREATE TRIGGER command followed by the INSERT INTO statement in the trigger's code. This will be capable of adding a row to the second table automatically whenever an action on the first table is performed. ... Read More
