a Below, write the content of a nonempty queue by filling in the following blank with a list of integers
such that calling ReverseAndRemoveOddsQ gives a WRONG result without raising any exception.
The size of the queue must be less than or equal to If such an input does not exist, write
"IMPOSSIBLE" in the blank.

c Below, write the content of a nonempty queue by filling in the following blank with a list of integers
such that calling ReverseAndRemoveOddsQ will result in a "maximum levels of recursion exceeded"
error. The size of the queue must be less than or equal to If such an input does not exist, write
"IMPOSSIBLE" in the blank.
Q: front
ackBelow is an attempt to implement a ReverseAndRemoveOddsQ operation on a queue Q The method is supposed to reverse the order of the items in the queue as well as removing all the odd numbers. However, the pseudocode is buggy.
Below is an example of a queue Q before and after ReverseAndRemoveOddsQ if the method worked correctly.
BEFORE: frontback
AFTER: frontback
Assume the following behaviour of the Queue methods.
Enqueueitem: enqueue at the back of the queue
Dequeue: dequeue at the front. Raise an exception if the queue is empty.
IsEmpty: returns whether the queue is empty.
void ReverseAndRemoveOddsQ x QDequeue; HelperQ x;
return;
void HelperQ item if QisEmpty
return;
x QDequeue; HelperQ x;
if item is even Enqueueitem;
return;
