In this problem, we are given a number N and we have to print all n-digit numbers whose digits are strickly increasing from MSB to LSB i.e. the number at LSB (left) should be smaller than the number at right.Let’s take an example to understand the problem −Input − n = 2Output −01 02 03 04 05 06 07 08 09 12 13 14 15 16 17 18 19 23 24 25 26 27 28 29 34 35 36 37 38 39 45 46 47 48 49 56 57 58 59 67 68 69 78 79 89.Explanation − as you ...

To get the threads of the running processes in the server using PowerShell you need to use Get-Process command. When you run this command default fields (ProcessName, Id, SI, CPU(s), WS(K), PM(K), NPM(K), Handles) will be displayed as a table.CommandGet-processOutputHandles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName ------- ------ ----- ----- ------ -- -- ----------- 502 27 9796 19340 1.72 6320 1 AcroRd32 640 52 112028 ...

Get-Process is a PowerShell cmdlet which used to get all the instances of the running background processes in the windows terminal. Whichever processes are displayed in the Task Manager Processes tab, all their threads can be displayed in the PowerShell console through Get-Process command.
To start dependent service in PowerShell, it is unlike the stopping the dependent services with –Force parameter because there is no –Force parameter is available.You need to first get the dependent services and then start them.Get-Service -Name Winmgmt -DependentServices | Start-Service -Verbose
To start multiple services with PowerShell, we need to use comma (,) between services.For example,Start-Service -Name Spooler,AdobeARMservice -VerboseGet-Service -Name Spooler,AdobeARMservice | Start-Service -VerboseTo start the services with display name,Start-Service -Name “Print Spooler”, “Work Folder” -Verbose Get-Service -Name “Print Spooler”, “Work Folder” | Start-Service -Verbose
In this problem, we are given a binary tree, a target node and an integer K. We have to print all the nodes of the tree that are at a distance K from the target node.Binary Tree is a special tree whose each node has at max two nodes (one/two/none).Let’s take an example to understand the problemK = 2Target node: 9Output −5 1 3.Explanation −The distance can be taken for node a higher, lower or at the same level. So, we will return nodes accordingly.To solve this problem we have to understand what are the types of nodes that are ... Read More
To stop the service using display name, use the parameter –DisplayName.For Example,PS C:\> Start-Service -DisplayName "Print Spooler" -Verbose VERBOSE: Performing the operation "Start-Service" on target "Print Spooler (Spooler)".You can also start the service with display name using,PS C:\> Get-Service -DisplayName "Print Spooler" | Start-Service -Verbose
To stop the service which has dependent service in PowerShell -Force parameter is used. First, we will check what are the dependent services for specific service, to get them -DependentService parameter is used.ExampleFor example, WMI service (Name: Winmgmt) has multiple dependent services.Get-Service -Name Winmgmt -DependentServicesOutputtatus Name DisplayName ------ ---- ----------- Running UALSVC User Access Logging Service Stopped smstsmgr ConfigMgr Task Sequence Agent Stopped SepLpsService Symantec Endpoint Protection Local ... Stopped NcaSvc ... Read More
In this problem, we are given a binary tree and two levels in the tree (upper and lower) and we have to print all nodes between upper and lower levels of the tree.The binary tree is a special tree whose each node has at max two nodes (one/two/none).Let’s take an example to understand the problem −upper − 1lower − 3Output −6 3 9 7 4 8 10To solve this problem, we have to print nodes of the tree at a given level. We will call a recursive function using a loop from the upper to lower level in the tree.This algorithm is simple ... Read More
To start a specific windows service, you need to use Start-Service command.ExampleStart-Service -Name SpoolerAbove command, will start the service name spooler. To check if service is started, use Get-Service –Name Spooler command.OutputStatus Name DisplayName ------ ---- ----------- Running spooler Print SpoolerThis command will not show the command progress. To check the command progress, use –Verbose parameter.PS C:\> Start-Service -Name Spooler -Verbose VERBOSE: Performing the operation "Start-Service" on target "Print Spooler (Spooler)".You can also start the service with, Get-Service -Name Spooler | Start-Service -Verbose PS C:\> Get-Service -Name Spooler | Start-Service -Verbose VERBOSE: Performing the operation "Start-Service" on target "Print Spooler ...
