Intro List methods are useful, and we have to use these most of the time when working with List. There are more than five methods. But I will write about the five most useful methods that I have used the most. Python List is equivalent to Array. So, if I use Array word instead of […]
Here is the link to the problem. See the problem description. We have to check the given array is monotonic or not. What is a monotonic array? “An array is monotonic if it is either monotone increasing or monotone decreasing.” line quoted from the problem description. The formula is:For checking increasing monotone of the given

If you know the basics of JavaScript, I can assume that you are familiar with JavaScript’s array. The array is a Data Structure to store more than one value. JavaScript has so many useful built-in array methods. Some methods we use frequently. Such as forEach, map, filter, etc. You may be familiar already. In this
Click here to see the problem details. The problem is simple. We have to find at least one duplicate in the given array. If we found any duplicate number, we will return True. Otherwise, we will return False. That’s the simple idea about the problem. And given array’s elements will be integers. Let’s see two

If you are familiar with at least one programing language, you already used array. It’s a linear and the most fundamental data structure of computer science. It’s comparatively easy to learn and very useful. In short, an array is a collection of elements. These elements can be any type of data type. Such as integer,
