Syntax : array.push(element1, element2, ..., elementN); Enter fullscreen mode Exit fullscreen mode *Example 1.: * const fruits = ["Apple", "Banana"]; fruits.push("Orange", "Mango"); console.log(fruits); // Output: ["Apple", "Banana", "Orange", "Mango"] Enter fullscreen mode Exit fullscreen mode *Example 2.: *How to Dynamically Add Elements Using the push() Method index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Fruit List</title> <link rel="stylesheet" href="https://dev.to/sudhanshu_developer/style.css"> </head> <body> <div id="container"> <h2>Fruit List</h2> <input…

Analyzing Algorithm Time Complexity

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

This section analyzes the complexity of several well-known algorithms: binary search, selection sort, and Tower of Hanoi. Analyzing Binary Search The binary search algorithm presented in BinarySearch.java, searches for a key in a sorted array. Each iteration in the algorithm contains a fixed number of operations, denoted by c. Let T(n) denote the time complexity for a binary search on a list of n elements. Without loss of generality, assume n is a power of 2 and k = logn. Since a binary search eliminates half of the input after two comparisons, Ignoring constants and nondominating terms, the complexity of…

Fui commitar e deu branco. E agora?

Esses dias, navegando no X, me deparei com a seguinte imagem E achei engraçado, porque eu e você provavelmente já nos vimos nessa situação: adicionamos os arquivos e ficamos literalmente travados pensando o que colocar de mensagem no commit. Muitas vezes os arquivos são em pastas e contextos diferentes, o que dificulta ainda mais a pensar em uma mensagem condizente. E é aí que mora o problema: Quando commitamos todos os arquivos com o famoso git add . fica muito difícil resumir em uma frase o que foi feito naquele commit. E você no fundo sabe que uma hora ou…

In web design, a horizontal navigation bar is a fundamental element allowing users to navigate different website sections. Creating a sleek and functional navigation bar using CSS (Cascading Style Sheets) is relatively straightforward and provides a lot of flexibility in terms of design and responsiveness.Here’s a step-by-step guide to creating your own horizontal navigation bar:Step 1: HTML StructureFirst, let’s set up the HTML structure for our navigation bar. We’ll use an unordered list (<ul>) to hold the list items (<li>) which will represent each navigation link. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Horizontal Navigation Bar</title>…

Problem description & analysis: Here is a categorized detail table: We need to group the table and concatenate the detail data using the semicolon. Solution: Use SPL XLL to do this: =spl("=E@b(?.groups(~1;concat(~2;$[;])))",A2:B9) Enter fullscreen mode Exit fullscreen mode As shown in the picture below: Explanation: E@b function converts the two-dimensional table to a sequence. ~1 represents the first sub-member of the current member; and $[] represents a string.

Vector and Stack Classes

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

Vector is a subclass of AbstractList, and Stack is a subclass of Vector in the Java API. The Java Collections Framework was introduced in Java 2. Several data structures were supported earlier, among them the Vector and Stack classes. These classes were redesigned to fit into the Java Collections Framework, but all their old-style methods are retained forcompatibility. Vector is the same as ArrayList, except that it contains synchronized methods for accessing and modifying the vector. Synchronized methods can prevent data corruption when a vector is accessed and modified by two or more threads concurrently. For the many applications that…

A few days before I participated in a jam to showcase my skills and see what other people are building, it was hosted on itch.io a famous place for hosting games and game jams. My Experience: The game jam hosts had given a time period of 10 days to finish a game by either using an engine or a framework.Like always I decided to make a game with pygame and choosing a difficult path for myself which gives more pleasure when completed. I only had last five days due to a work load in the previous days. After thinking a…
