In this problem, we are given a string and an integer M. our task is to print all distinct circular strings of length M in lexicographical order (alphabetical order).Let’s take an example to understand the problem, Input: str= “ssssn” M=3 Output: nss sns ssn sssExplanation − all possible circular strings of length 3 are: sss sss ssn sns nss. Distinct elements in lexicographical order are sss ssn sns nss.To solve this problem, we will iterate over the elements of the string and generate all possible substrings of length M. we will store this generated string in a set that stores ...

To stop running all the instances of the process in PowerShell Stop-Process command is used. For example, in the below example, we have two running instances of notepad.exe process.CommandPS C:\WINDOWS\system32> Get-Process notepadOutputPS C:\WINDOWS\system32> Get-Process notepad Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName ------- ------ ----- ----- ------ -- -- ----------- 228 13 3160 13448 0.14 15564 1 notepad 228 14 3148 13668 0.17 22644 ...

To get the output in gridview format in PowerShell, you need to Pipeline the Out-GridView variable so the output will be in GUI format.CommandGet-Process | Sort-Object CPU -Descending | Select -First 10 | Out-GridView -Title "Top 10 CPU usage processes"
To display only the first 5 processes you need to use –First parameter in the Select-Object pipeline statement. You can use multiple filter statements and later at last pipeline the –First command to display only a few results.CommandGet-Process | Select -First 5OutputHandles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName ------- ------ ----- ----- ------ -- -- ----------- 498 26 9736 18624 2.27 6320 1 AcroRd32 624 51 112048 ...

Get-Process shows the default properties only. To get all the properties of Get-Process, we need to pipeline Format-List * (fl *).Get-Process | Format-List *OutputName : AcroRd32 Id : 8052 PriorityClass : Normal FileVersion : 11.0.23.22 HandleCount : 616 WorkingSet : 17453056 PagedMemorySize : 114597888 ...

In this problem, we are given an array of integer values. Our task is to print all distinct elements of the array. The output should contain only distinct values.Let’s take an example to understand the problemInput: array = {1, 5, 7, 12, 1, 6, 10, 7, 5} Output: 1 5 7 12 6 10To solve this problem, we will have to check elements of the array for uniqueness. For this, we will use two nested loops, the outer one will take values and the inner one will check the rest of the values with it. If more than one values ... Read More
You can group the processes based on their properties. Here, we will group the processes based on their name, it would display how many instances of the process is running. Group-Object command is useful for it.CommandThe below command will group the object and sort the object based on their thread counts.Get-Process |Group-Object Name | Select Name, Count |Sort-Object count - DescendingOutputName Count ---- ----- svchost 91 chrome 34 RuntimeBroker 11 conhost 6 Code 6 WmiPrvSE 6 dllhost 4 RAVBg64 4 powershell 3 csrss 2 fontdrvhost 2 AcroRd32 2 taskhostw 2 SkypeBridge 1 smartscreen 1 smss 1 sihost 1 SkypeApp 1 SkypeBackgroundHost 1 sppsvc 1 StartMenuExperienceHost 1
To find the specific process using Get-Process cmdlet, you need to use the –Name parameter. You can use single and multiple process names.CommandGet-Process -Name AcroRd32, audiodgOutputHandles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName ------- ------ ----- ----- ------ -- -- ----------- 506 27 9888 19216 2.22 6320 1 AcroRd32 632 51 112196 17648 42.95 8052 1 AcroRd32 209 13 10344 17100 13.98 22748 0 audiodgYou can also achieve the same using Where-Object (alias: Where) command.Get-Process | Where{$_.Name -eq "AcroRd32"} But to get the multiple processes you need to use the –OR comparison operator.Get-Process | Where{($_.Name -eq "AcroRd32") -or ($_.Name -eq ...

In this problem, we are given an array of N integers and a number K. Our task is to print all distinct numbers that can be created by adding any K elements from the array. While choosing any number can be repeated K times.Let’s take an example to understand the problem −Input: array = {2, 5, 13, 9} K = 2 Output: 2, 7, 15, 11, 10, 18, 14, 26, 22 Explaination: 2 elements added : 2+2=4, 2+5=7, 2+13=15, 2+9=11, 5+5=10, 5+13=18, 5+9=14, 13+13=26, 13+9=22, 9+9=18To solve this problem, we will find all combinations of the k element from the ...
