6.7 LINKED QUEUES
We know that a queue is a FIFO (first in first out) data structure. Since this data structure also involves
deletions and additions at front end and rear end respectively, a linked list is definitely a better choice
from the point of implementation.
A linked queue will have the same node structure as in the case of a stack as shown in Figure 6.35.
Two pointers called Front and Rear would keep track of the front and rear end of the queue.
