b) i) Given the following code fragment: String str = "practice makes perfect"; Queue stringQ = new Queue (); Queue spaceQ new Queue () ; for (int i = 0; i< str.length (); i++) { if (str.charAt (i) >= 'a'&& str.charAt (i) <= 'k') stringQ.enqueue (str.charAt (i)); if (str.charAt (i) == ' ') spaceQ.enqueue (i); Draw two queue diagrams to represent stringQ and spaceQ elements after the code fragment has been executed. Label the diagrams with front and rear of the queues. perks) ii) Find the output of the following program code if the following values have been inserted into abcQ: 1 2 3 4 5
