Implementation of queue by using a single linked list, Data Structure & Algorithms

Assignment Help:

Q. Perform implementation of a queue using a singly linked list L. The operations INSER and DELETE should take O (1) time.                                                                           

Ans:

Implementation of queue by using a singly linked list:

When implement a queue as a single liked list, a queue q consists of a list and two pointers, q.front and the q.rear.

inserting an element is stated below:

insert(q,x)

{

p=getnode(); info(p) = x; next(p) = null; if(q.rear == null)

q.front = p;

else

next(q.rear) = p;

q.rear = p;

}

deletion is stated below:

remove(q)

{

if(empty(q))

{

printf("queue overflow");

exit(1);

}

p=q.front; x=info(p); q.front=next(p); if(q.front == null) q.rear = null; freenode(p); return(x);

}
