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
O(n)
O(nk)
O(n+k)
O(n^2)
