Introduction The kernel is the core component of a Linux-based operating system, and it is responsible for managing the system's resources and communicating with hardware devices. Whenever a new version of a kernel is released, it typically includes important bug fixes, security patches, performance improvements, and other enhancements that can improve the overall functionality and stability of the system. However, when multiple versions of the kernel are installed on the same machine over time, they can take up valuable disk space and slow down system performance. Deleting old unused kernels is an essential maintenance task that helps keep your Linux-based ... Read More
The tag is used to specify a division. It means a container or a section in an HTML page. Sometimes, inside a div container, text and icons are both needed. And sometimes, the need is to align the text on the left while putting the icon on the right in the same line. The CSS or Cascading Style Sheets means style specifications that are used for formatting an HTML document. It is used to give the style to the web page and its elements. In this HTML-CSS article, using three different examples, the ways to show how to ... Read More
In the arena of web development, Django has emerged as a famous, open−source, and high−stage Python internet framework that encourages fast improvement and easy, pragmatic design. Django boasts a robust form of coping with devices, which allows developers to create, validate, and technique paperwork effortlessly. One essential component of Django's shape dealing with devices is its potential to render forms as HTML tables. In this post, we will go through the procedure of rendering Django forms as tables, which include the blessings, how to gain this, and a few exceptional practices to observe. By the end of this post, you ... Read More
There is a famous maximum sum subarray problem, in which we have a 1 Dimensional array and must find the maximum sum in that subarray. To solve this problem, the most naive approach will be to find all the sub − arrays, sum their elements, and return the maximum, but the time complexity will be O(N*N). To reduce this there is an algorithm that will reduce the time complexity from O(N*N) to O(N) named as Kadens Algorithm. In programming, there are algorithms based on the Dynamic programming concept in which the problem is broken into sub − problems and the ... Read More
In programming, to search for anything from an array, linked List, or any other data structures we have a few search algorithms, one of which is binary search. In binary search, the prerequisite is that the data should be sorted. In binary search, we follow the divide and conquer approach in which we divide the data by applying some conditions and then perform the operation on that data only. In this way, we reduce the time complexity. For example, if we have an array of elements {20, 44, 45, 54, 67, 88, 91} and we want to find 44 then ... Read More
In Golang, like other programming languages, we can find the union of two arrays. The union of two arrays is a list that consists of elements that lie in array A and the elements that lie in array B and common elements that lie in both arrays. For example, we have two arrays listed below A = {2, 9, 5, 7, 3} B = {5, 8, 7 2, 1} The union of the above arrays will be Union = {1, 2, 3, 5, 7, 8, 9} Method 1 In this method, we are going to find the union of two ...

In programming languages, we can create 2−Dimensional Matrices and store elements in them. The 2−Dimensional metric is a data structure that has rows and columns. In this article, we are going to see the two different logic to find the maximum no. of ones in a sorted row of the matrix. For example, we have below the matrix {0, 1, 1, 1}, no. of 1s = 3 {0, 0, 1, 1}, no. of 1s = 2 {1, 1, 1, 1}, no. of 1s = 4 {0, 0, 0, 0}, no. of 1s = 0 In the ... Read More
In programming, there is a problem statement asked in interviews to find the duplicate number in an array of size N + 1. Also, there will be only one duplicate element in the array. The elements will be between 1 to N. For example, Array = {1, 3, 2, 1, 4} 1 is the duplicate element in the above array. Algorithm Step 1: Import the required packages at the top using the import keyword. Step 2: Then the main function will get run first. First, we are declaring and initialize the array. Now, we are calling the function to ... Read More
In programming, there are different data structures to store data. There are two different types of data structures linear and non −linear. Array, stack, queue, and linked list are linear data structures. Binary trees, trie, etc are non − linear data structures. In this article, we are going to explore level order traversal on one of the non − linear data structures i.e. binary tree. Level Order Traversal In level order traversal, of a binary tree we start from the root node and then traverse the children nodes and move to the children of children nodes. In this way, ...

In programming, there is a coding problem of binary tree that gets asked very frequently in interviews and the problem statement is to find the left view of a binary tree. If we try to understand the problem statement more than what exactly the left view is then we can explain it in a way that all the nodes are visible when you see them by standing on the left side of the tree. Illustration Let us understand more with the help of an example. Suppose we have a below tree and if we stand on the left side ... Read More
