2) What item is at the front of the list after these statements are executed?
DequelnterfacexString> waitingLine = new LinkedDeque<>();
waitingline.addToFront/"Jack");
waitingLine.addToFront("Rudy");
waitingLine.addToBack/"Larry");
waitingLine.addToBack/"Sam";
String name = waitingLine.getFront();
a) jack
b) Rudy
c) Larry
d) Sam
6) a linked chain implementation of a queue, the performance of the enqueue operation is
O(1)
OO(log n)
O(n)
O(n^2)
7) In a linked chain implementation of a queue, the performance of the getFront operation is
O(1)
O(log~n)
O(n)
O(n^2)
8) In a circular array-based implementation of a queue, what is the performance when the enqueue operation must resize the array?
O O(n^2)
O(n)
O(log n)
O(1)
