In this article, we create a function that takes in a number(num) which represents the number of seconds. So, it construct and return a string that contains information of years, days, hours and minutes contained in those seconds. Converting seconds into years, days, hours, and minutes in JavaScript involves breaking down a given total of seconds into more understandable time units. This process helps display elapsed time in a readable format. For the purpose of the article, we will consider that all the years have 365 days. Let us understand through some sample example of I/O Scenario − Sample Input ... Read More
Satellite-based tracking is an essential feature of many products and services in today’s increasingly connected world. This kind of tracking allows users to effectively follow devices as they move around on a global scale, and have up-to-the-second information on their position. But how does this innovative and powerful tracking system work, and how does its software play a key role in it? GPS Overview The Global Positioning System (GPS) is a feat of modern-day technology that accurately provides the position of a tracked item regardless of the weather, at any time of day or night. Run and owned by the ... Read More

Problem Description In this problem, we are given two numbers, and we have to find the value obtained after adding one number to another. In this article, we are going to learn how we can add two numbers in PHP using different approaches. Example 1 Input $number1 = 8; $number2 = 12; Output 20 Explanation The addition of $number1 + $number2, i.e., 8 + 12, will give 20 as result. Example 2 Input $number1 = 10; $number2 = 10; Output 20 Explanation The addition of $number1 + $number2, i.e., 10 + 10, will result in 20. Below ... Read More
