When QueueADT is implemented using a circular array, what is the worst case runtime complexity of the operation if problem size is the number of initialized elements in the array and the queue is NOT full? True or False: the enhanced for loop presented in the static method will set all the elements of the list to 100.0. True False When a StackADT is implemented using a doubly linked list, which of the following is a MORE efficient implementation? Having the top of the stack at the head of the list. Having the top of the stack at the tail of the list. Both choices are equally efficient. True or False: a class which implements the lterable G (https://docs. oracle.com/en/java/javase/17/docs/api/java. base/java/lang llterable.html). interface may be used in an enhanced-for loop. For example: Iterable myIterableList =/ create this object correctly /; for (String s : myIterableList) \{ System. out.println(s); \} True False
