Definition - unix operating system

Unix is a portable, multitasking, multiuser, time-sharing operating system (OS) originally developed in 1969 by a group of employees at AT&T.

Unix has been ported to more machine families than any other operating system. As a result, it has come to be identified with the concept of open systems. Unix operating systems are widely used in PCs, servers and mobile devices. The Unix environment was also an essential element in the development of the Internet and networking.

1- Use LinkList. Write removeLast(n). Delete the last occurrence of an item from a linked list. So if the item is 7 and the list is [1,3,7,4,7,3,7,2], the result is [1,3,7,4,7,3,2] 2- Use LinkList. Write removeAll(int n). Deletes all occurrences of an item n from a linked list. So if the item is 7 and the list1 is [1,3,7,4,7,3,2] , then list1.removeAll(7) then list1 becomes [1,3,4,3,2]. Demonstrate by displaying the list contents before and after calling the above methods. Eg:...
