To start the specific task of the task scheduler using PowerShell, we need to use the Start-ScheduledTask command.When we run the above command, we need to provide the task name.For example, Start-ScheduledTask -TaskName 'FirstTask'When you check the above task status, ExampleGet-ScheduledTask -TaskName 'FirstTask'Output:TaskPath TaskName State -------- -------- ----- \ FirstTask RunningTo start the task on the remote computer, we first need to connect to the CIMSession of the remote computer and we can use the below command.$sess = New-CimSession -ComputerName Test1-Win2k12 Get-ScheduledTask -CimSession $sess -TaskName 'FirstTask' | Start-ScheduledTaskWe can also start the task directly with the command, Start-ScheduledTask using the CIMSession.Start-ScheduledTask -TaskName 'FirstTask' -CimSession $sessRead More
To retrieve the existing tasks in the task scheduler using PowerShell, we can use the PowerShell command Get-ScheduledTask. We can use the Task Scheduler GUI to retrieve the scheduled tasks. To retrieve using PowerShell, use the Get-ScheduledTask command.When we use the above command, it retrieves all the tasks from the different paths/folders as well including the root path. To retrieve tasks created at the root path we need to filter the task path, Get-ScheduledTask | where{$_.TaskPath -eq "\"}If we need to retrieve the specific task then we need to filter the task name, TaskPath TaskName ...

Suppose we have two strings s and t. We have to find the smallest substring in s, where t is also a subsequence of the substring. If that type of substring does not exist, we will return a blank string, and if there are multiple smallest substrings, we will take the leftmost one.So, if the input is like s = "abcbfbghfb", t = "fg", then the output will be fbgTo solve this, we will follow these steps −N := size of Sdp := a new list of size N initialized with infinityfor i in range 0 to N − 1, ...

Suppose we have to implement a class named MedianClass which contains the following methods −add(value) which adds a value to the data structure.median() finds the median of all the numbers currently present in the data structure.So, if we add 5, 3, 8 and find median, the output will be 5.0, then if we add 9 and find the median, the output will be 6.5.To solve this, we will follow these steps −Define priority queue left and rightDefine addNum method, this will take the number as input −if left is empty or num < top element of left, then, insert num ...

Suppose we have an integer n, we have to find the number of positive integers that are less than or equal to n, where the integer numbers at least have a digit occurring more than once.So, if the input is like n = 200, then the output will be 38To solve this, we will follow these steps −Define an array afor initialize x := n, when x is non−zero, update x := x / 10, do −insert x mod 10 at the end of areverse the array aret := nfor initialize w := 1, d := 1, when w < ...

Suppose, we have a lowercase string s that contains letters and parentheses "(" and ")". We have to reverse every string enclosed within parentheses in a recursive manner and return the resultant string.So, if the input is like s = "back(aps)ce", then the output will be “backspace”.To solve this, we will follow these steps −Define a function trav() . This will take s, dir, start, close:= close, ans:= ansend := "(" if dir is same as −1, otherwise ")"other := "(" if end is same as ")", otherwise ")"while start < size of s, and s[start] is not same as ...

Suppose, we have a car and are driving it on a one−dimensional road. Currently we are at position = 0 and with speed = 1. We can perform any of these two operations.Acceleration: position := position + speed and speed := speed * 2 Reverse Gear: speed := −1 when speed > 0 otherwise speed := 1.We have to find the number of moves needed at least to reach the target.So, if the input is like target = 10, then the output will be 7.To solve this, we will follow these steps −Define a function dfs() . This will take ... Read More
Suppose we are playing a unique game and we have three values n, k, and h. We start from 0 points, then we can select a number randomly between 1 and h (inclusive) and we will get that many points. We stop when we have scored a minimum of k points. We have to find the probability that we have n or fewer points. Here any number can be chosen randomly and the outcomes all have the same probability.So, if the input is like n = 2, k = 2, h = 10, then the output will be 0.11.To solve ... Read More
Suppose we have a list of numbers. We have to find the length of the longest sequence of numbers such that when we delete a number from the sequence, each number occurs the same number of times.So, if the input is like numbers = [2, 4, 4, 7, 7, 6, 6], then the output will be 7.To solve this, we will follow these steps −num_freq := a new mapfreq_freq := a new mapdiff_freq := a new setresult := 1for each index I and value num in nums, docur_freq := num_freq[num]num_freq[num] := num_freq[num] + 1freq_freq[cur_freq] := freq_freq[cur_freq] − 1freq_freq[cur_freq + 1] ...

Suppose, we are provided with a list of numbers called nums. Here we can jump to index i + numbers[i] or to i − numbers[i] from index i if the values exist in the list. So we have to find the number of jumps required at least to reach another value with different parity keeping the order in the input unchanged. If we cannot reach another number with different parity, it is set to −1.So, if the input is like numbers = [7, 3, 4, 5, 6, 9, 6, 7], then the output will be [−1, 1, 2, −1, −1, ... Read More
