In this problem, we are given a number n. Our task is to print patterns with decreasing to 0 or negative then increasing back to the number.Let’s take an example to understand the problem,Input: n = 12 Output: 12 7 2 -3 2 7 12To solve this problem, we will use recursion and call the function after each update. The track of update is kept using the flag variable which tells the function to increase or decrease the number by 5.ExampleThe below code gives the implementation of our solution, Live Demo#include using namespace std; void printNextValue(int m){ if (m > 0){ cout

To display the directory content, Get-ChildItem cmdlet is used. You need to provide the path of the directory or if you are in the same directory, you need to use only Get-ChildItem directly. In the below example, we need to display the contents of the D:\temp directory.When Get-ChildItem command is run outside of this directory then the path of the directory should be provided. This is called the absolute path.PS C:\> Get-ChildItem D:\Temp\CommandWhen this command is run directly within the directory then simply run this command. This is called a relative path.PS D:\Temp> Get-ChildItem OutputDirectory: D:\Temp Mode ... Read More

In this problem, we are given a number. And we have to print all 3 digit repeating numbers.Let’s take an example to understand the problem, Input: 98769876598765 Output: 987: 3 times 876: 3 times 765: 2 timesTo solve this problem, we will use the large number which is stored string. The digits of the numbers are counted as characters. Now, we will check the first three numbers and then start from the 3rd index to the end and get a new number. After this, we will check for the next 3 digit numbers are count its frequency. ... Read More
