Good problem-solving in computer science heavily relies on efficient algorithms like the Greedy-Best First Search (GBFS). GBFS has already established credibility as an optimal solution method for pathfinding or optimization issues. Therefore, we're discussing GBFS thoroughly in this article while exploring its implementation approach using C++. Syntax void greedyBestFirstSearch(Graph graph, Node startNode, Node goalNode); Algorithm The Greedy Best-First Search algorithm aims to find the path from a given start node to a goal node in a graph. Here are the general steps of the algorithm − Initialize an empty priority queue. Enqueue the start node into the priority ... Read More

The add user command in Linux is used to add new user accounts on operating systems that resemble Unix. It is frequently used by system administrators to add new users with predetermined usernames, passwords, and other user-related information System calls Software can communicate with the kernel of the operating system, which manages system resources and provides services to user-level programs, through system calls. System calls are used in C programming to gain access to the features and services provided by the operating system, including file I/O, process management, network connectivity, and more. To interact with the operating system, C programmers ... Read More
