Discuss whether an Array, LinkedList, Stack or a Queue data structure is the appropriate structure for determining the order in which elements are processed in each of the following situations:

(a) Batch computer programs are submitted to the computer situations.

(b) Program A calls subprogram B which calls subprogram C, and so on.

(c) Employees have a contract, which calls for a seniority system for hiring and firing.

You need to describe the reason to choose appropriate data structure as well as describe the in very short about the particular data structure definition for the above situations.
