Hi,
Now the maximum number of element i can insert in the queue(q1 or q2 or q3 ) is 5.
After inserting 5 elements in one of the queue, if i try to insert any more element,
that element will automatically go to wait queue.Now what i want is if i remove one
element from the say q1(which already had 5 elements)manually.one element from wait queue
must get inserted in the q1 at last position automatically.
I have given my program below. Can anyone please help.
