In computer networks, congestion occurs when data traffic exceeds the available bandwidth and leads to packet loss, delays, and reduced performance. Traffic shaping can prevent and reduce congestion in a network. It is a technique used to regulate data flow by controlling the rate at which packets are sent into the network. There are 2 types of traffic shaping algorithms: Leaky Bucket Token Bucket

Getting ready for a tech job interview? Algorithms are really important! Companies often ask questions that require problem-solving skills. In this article, we'll look at the top 10 algorithms commonly used in interviews. Each algorithm is like a powerful tool in your problem-solving toolbox. Knowing them well can really help you handle different technical challenges during interviews. Let's break

Algorithm is a step-by-step procedure for solving a problem or accomplishing a task. In the context of data structures and algorithms, it is a set of well-defined instructions for performing a specific computational task. Algorithms are fundamental to computer science and play a very important role in designing efficient solutions for various problems. Understanding algorithms is essential for any

Given an array arr[] of size N, the task is to find the length of the Longest Increasing Subsequence (LIS) i.e., the longest possible subsequence in which the elements of the subsequence are sorted in increasing order, in O(N log N). Examples: Input: arr[] = {3, 10, 2, 1, 20} Output: 3 Explanation: The longest increasing subsequence is 3, 10, 20 Input: arr[] = {3, 2} Output:1 Explanation: The long

Given an undirected graph with V vertices and E edges (edges[][]), Your task is to return all the articulation points in the graph. If no such point exists, return {-1}. Note: An articulation point is a vertex whose removal, along with all its connected edges, increases the number of connected components in the graph. The graph may contain more than one connected component.Examples: Input: V = 5,

In C, the extern keyword is used to declare a variable or a function whose definition is present in some other file. Basically, it extends the visibility of the variables and functions in C to multiple source files. Before going deeper into the topic, we need to know about a few terms: Declaration: A declaration only tells the compiler about the existence of an identifier and its type.Definition:
