Course Introduction:Use the os.Chown function to modify the owner and group of a file or directory. In the operating system, files and directories have an owner and group. The owner refers to the user who created the file or directory, and the group belongs to the user group to which the user belongs. Sometimes we need to modify the owner and group of a file or directory to better manage and control file access permissions.

Course Introduction:In C#, the Array class has a read-only property called LongLength. It returns a long integer value indicating how many elements the array can hold. Only arrays of rank one or higher, that is, non-single-dimensional arrays, can access the LongLength property. Although the LongLength property provides long values, it is important to remember that the maximum size of an array in C# is still limited by the amount of memory supported by the system. If you try to build an array that is too large, an OutOfMemoryException may be thrown. Syntax publiclongLongLength{get;}Long-64-bit integer value, indicating the number of elements in the array. The number of elements in the entire array is passed in C#

Sometimes, we need to filter objects from an array of objects based on specific properties. For example, we have an id as a key that identifies an object. Therefore, we need to ensure that the array only contains a single object with a single id. If two or more objects contain the same primary key value, this can lead to problems with object unique identification. Here we will learn different ways to filter all unique objects from an array based on specific properties. Using Maps and for Loops In JavaScript, Maps can store unique key-value pairs. Furthermore, we can get any value from the Map using the Map's keys with O(1) time complexity. So we will iterate over the array of objects and put the key value
