Consider the following operation along with Enqueue and Dequeue operations on queues, where k is a global parameter.
MultiDequeue(Q){
m = k
while (Q is not empty and m > 0) {
Dequeue(Q)
m = m - 1
}
}
What is the worst case time complexity of a sequence of n MultiDequeue() operations on an initially empty queue? (GATE CS 2013) (A) 
(B) 
(C) 
(D) 
(A)
A
(B)
B
(C)
C
(D)
D
Answer: (A)
Explanation:
Since the queue is empty initially, the condition of while loop never becomes true. So the time complexity is .
Hence Option (A) is the correct answer.
