Data Structure - Priority Queue

Items in a priority queue are entered in a random order. Priority queue contains data items which have some preset priority. While removing an element from a priority queue, the data item with the highest priority is removed first.
In a priority queue, insertion is performed in the order of arrival and deletion is performed based on the priority.

CORRECT ANS

n a priority queue, an element with high priority is served before an element with low priority.

random is a sub type of "as and when they come"

"as and when they come" is correct. It does not exclude "random" but allows for a specific order if the program gives one.

Data structure & Algorithm

no in priority queue elements are entered randomly. the order of priority is maintained when they are processed. and here processing means deletion from the queue. so the element with the highest priority is deleted at the begining. if more than 1 element have the same priority then fifo i.e first in first out order is followed!! suppose D with max priority 4 is deleted at first. then element with priority 3 is to be deleted. now suppose A and B both have priority 3. that case the element which has entered in the queue before will be processed and deleted, then the next one. after elements with priority 3 deletd, then elements with priority 2 is to be processed!! (CONSIDERING PRIORITY ORDER 1<2<3<4)

Ds

The data should be inserted as they come but priority order should be maintained

data structure

the answer "random" is wrong. How would you define random. @chandini is half way correct. The correct answer should be c "as when they come" which implies random.

Data structure

priiroty queue is implemented using two queue.one to hold data and another to hold priority.Hence data in data queue can be in random order.

As per my view in priority queue the elements are entered in the basis of order of priority...if two items have the same priority it looks for the queue order..
