We are given an array it this problem and we have to remove all the elements of the array with the minimum cost required. We have to remove two elements at a time and add them to the total cost. Also, we can remove the third number without any cost if we remove two elements and the third element's value is at most equal to the minimum of them. Also, it is given that the given array will be of a size greater than 1. Sample Examples Input int arr[] = {7, 6, 5, 2, 9, ... Read More
Moving a list of folders with subfolders is a common task when working with large files or organizing data. Python offers several approaches to handle this task, each with their own advantages and disadvantages. In this article, we will learn how to move a list of folders with subfolders using Python. We will see the different approaches along with their syntaxes and examples to moving a folder list with subfolders using Python. How python helps in moving list of folders with subfolders? Python is a popular programming language that provides a variety of built−in functions and modules to handle ... Read More
We are given an array that contains the binary numbers that are '0', and '1' only. We have to make a one-bit set of the given array which was earlier not the set bit (there will be at least a bit present in the given array which will not be a set bit) to set bit such that the number of indexes present in between the set bits of the final array will be at the maximum distance possible. Sample Examples Input int arr[] = {1, 0, 0, 0, 0, 0, 1, 1, 0, 0, 1, 0, ... Read More
Data in today’s time is generated in large volumes, and organizing that data can be a challenging task. One of the most common issues people face is merging multiple folders into one. It can be quite frustrating to search for a specific file when you have multiple folders to navigate through. Fortunately, Python provides a simple solution to this problem. In this article, we will learn how to merge multiple folders into one folder using Python. To merge multiple folders into one, we will be using the os module that provides a portable way of using operating system−dependent functionality like ... Read More
Excel is one of the most popular tools for data analysis and management. Often, we need to merge multiple Excel files into a single file for analysis or sharing with others. Manually merging these files can be time−consuming and prone to errors, especially when dealing with large datasets. Luckily, Python provides an efficient and flexible way to merge multiple Excel files into a single file. In this article, we will learn how to merge multiple Excel files using Python. We will be using the Pandas library, which is a powerful and easy−to−use data analysis library for Python to merge the ... Read More
If you work with data, you've probably had to deal with the challenge of merging multiple files into one cohesive dataset. This task can be particularly difficult if you're working with tab−separated values (TSV) files. Fortunately, the Python Pandas library provides a straightforward solution for merging TSV files by a common key. In this article, we'll learn how to merge multiple TSV files using Python Pandas. To begin with, we will first see what TSV files are and how they differ from CSV files. Next, we'll see the Pandas library and explain its capabilities for working with TSV files. And ... Read More
There are two players, X and Y, who are playing a game. X will start the first and can pick 1 stone from the set of an unlimited number of stones after that Y will start and can pick the 2 stones, then X will pick 3, and so on the game will go alternatively until the sum of the total stones picked by X is less than or equal to the given number A or the sum of total stones picked by Y is less than or equal to another given number B. If the current sum of any ... Read More
In the world of image processing, merging two or more images together is a common operation. One common use case is to merge a transparent PNG image with another image to create a composite image that contains both images. In this article, we will learn how to merge a transparent PNG image with another image using PIL. PIL is a powerful library for working with images in Python. It provides a range of functions for opening, manipulating, and saving different types of image files. The library is compatible with a wide range of image formats, including JPEG, PNG, BMP, ...

Peaks are defined as the point or index in the array where are both left and right sides values are smaller than the value of that index. And Troughs are defined as the point or index of the array where are both left and right sides values are greater than the value of that index. In this problem, we have given an array 'array' of size n of integers. Our task is to minimize or reduce the count of peaks and troughs of the given array by performing an operation. Operation is that we can replace at most one value of the ... Read More
We are given two strings and we have to check if it is possible to convert the first string to another by performing any number of times a particular given task. The tasks that can be performed on the given first string only and the tasks are: Choose any index i such that i < length(A) -1 and swap ith character with the next character. We are given an integer k and we can choose any consecutive k indexes of the first string only if they are ... Read More
