$8$ In this assignment, you will be implementing your own Array $-$ Based Stack $($ABS$)$ and Array $-$ Based Queue$($ABQ$).$ A stack is a linear data structure which follows the Last $-$ In$,$ First $-$ Out $($LIFO$)$ property. LIFO means that the data most recently added is the first data to be removed. $($Imagine a stack of books, or a stack of papers on a desk$-$the first one to be removed is the last one placed on top.$)$ A queue is another linear data structure that follows the First $-$ In$,$ First $-$ Out $($FIFO$)$ property. FIFO means that the data added first is the first to be removed $($like a line in a grocery store$-$the first person in line is the first to checkout$)$
