Nuget is the package management tool for the .NET and it is similar to PowerShellGet, MSI packages which support several commands and packages to work with PowerShell.NuGet supports Install−Package, Update−Package, Find-Package, and Get−Package command and if Nuget package is not installed in your system, you may not find a package or install any package.For more reference about Nuget, check the websites below.https://www.nuget.orghttps://docs.microsoft.com/en-us/nuget/reference/powershellTo install NuGet, we need to use the Install−PackageProvider command. Use the below command to install the Nuget package.Install−PackageProvider −Name Nuget −ForceOn some machines, you will get the error message regarding downloading the package from the internet. If you ... Read More
we often deal with nested lists when doing data analysis in python. In this article, we will see how to find out the longest list among the elements in a nested list and then print this along with its length.Using lambda and mapWe declare a nested list and give it as input to the lambda function along with its length. Finally, we apply the max function to get the list with maximum length as well as the length of such list.Example Live Demodef longest(lst): longestList = max(lst, key = lambda i: len(i)) maxLength = max(map(len, listA)) return longestList, ...

To change the drive letter using PowerShell, we can use the Set−Partition command but before that, we need to know which drive letter to change. You can check the drive letter using Windows Explorer, Get−Partition, Gwmi win32_Logicaldisk, or Get−CimInstance Win32_Logicaldisk command.Suppose we have an E: and we need to rename its drive letter to F, so we can use the below command.Set−Partition −DriveLetter 'E' −NewDriveLetter 'F'Make sure that the drive is not in use by Pagefile, open application, or open file from the drive otherwise the drive letter will fail to change.To change the drive letter on the remote computer, ...

To get the Windows disk information using PowerShell, we can use the WMI command or the CIM class command.With the WMI command, Gwmi Win32_LogicalDiskWith the CIM instance method, Get−CimInstance Win32_LogicalDisk You can see both the outputs are identical. Let’s use one of them.DeviceID DriveType ProviderName VolumeName Size FreeSpace -------- --------- ------------ ---------- ---- --------- C: 3 53317988352 44027125760 D: 5 HRM_SSS_X64FREE_EN-US_DV5 3694962688 0 E: 3 Temporary Storage 10734268416 10238513152Now there are different drive types associated with Windows and they each have an identical number. For example, Drive Type ‘3’ mentions the logical disk. The other types are as below.2 = ... Read More
Where−Object or (alias: Where) in PowerShell is used to filter the data output provided through the Pipeline.There are two methods we can use the Where−Object for the pipeline inputs.a. ScriptMethod −In this method, we use ScriptBlock to filter the output with the Property name, value, and the comparison operator.Get−Service | Where−Object{($_.StartType −eq 'Automatic') −and ($_.Status −eq 'Stopped')}You can also use Alias: Where instead of Where−Object.Get−Service | Where{($_.StartType −eq 'Automatic') −and ($_.Status −eq 'Stopped')} Other Syntax ‘?’ (Question Mark) can also be used Instead of the Where−Object command.Get−Service | ?{($_.StartType −eq 'Automatic') −and ($_.Status −eq 'Stopped')}The above commands will get the ...

In this problem, we are given two strings str1 and str2. Our task is to create a program to Print all possible ways to convert one string into another string. Problem Description: Here, we need to find all possible ways using which we can convert str1 to str2. While converting, we can perform any of the three operations, Insert RemoveReplaceLet’s take an example to understand the problem, Input: str1 = “kfeod” str2 = “kfcadq”OutputWay1:Insert q, after d. Replace c by e. Replace o by a.Solution ApproachWe will find the minimum number of edits first and then create a DP matrix. Then check if the character ... Read More
In this problem, we are given two values k1 and k2 (k1 < k2), and the root of the binary search tree. Our task is to create a program to Print BST keys in given Range. Problem Description: We will print all the keys of the tree from n1 to n2 in increasing order.Let’s take an example to understand the problem, Input: k1 = 4, k2 = 12Output: 6, 7, 9Solution ApproachSimple we can solve the problem using inorder traversal but the space complexity there is 0(n) but the need of the hour is to solve in O(1) complexity. So, for this, we will use a ... Read More
In this problem, we are given a matrix mat of size mXn of integer values. Our task is to create a program to Print cells with same rectangular sums in a matrix.Problem description: We will be finding a cell in the matrix in such a way that the sum of sub-matrices that are starting and ending with the cell is equal to the sum of all the remaining elements. For a cell the sum of matrix (a, b) sub-matrix mat[0][0] to mat[a][b] and mat[a][b] to mat[m][n] is equal to the sum of all remaining elements.Let’s take an example to understand the problem, ...

In this problem, we are given an array arr[] of size n consisting of positive and negative values and an integer k. Our task is to find the maximum average subarray of k length. Let’s take an example to understand the problem, Input: arr[] = {4, -1, 5, 6, -2, 4} k = 3Output: 10Explanation: The subarray of size 3 with max sum is -1, 5, 6 = 10Solution ApproachA solution to the problem is done by using an auxiliary array to store cumulative sum till the current index in the array.To find the sum of subarrays, we need to compute the difference between the indices ...

In this problem, we are given an array arr[] of size n consisting of positive values. Our task is to find maximum in an array without using Relational Operators. Let’s take an example to understand the problem, Input: arr[] = {5, 1, 6, 7 , 8, 2}Output: 8Solution ApproachSince we need to compare values without using logical operators. For this we need to perform repeated subtraction, the number which will last longer will be the larger one.We will decrement all values by one till they become zero. We will start with the first two values of the array and find the greatest ... Read More
