c) Based on the following program segment, draw the representation of stack A, B and C after the execution of the line of codes as indicated by Structure-A1, Structure-B1, and Structure-C1 respectively. In the diagram of the stack representation that you have drawn, you are to indicate the base and the top of the data. After that, show the output the program. Hint: A, B and C are the instances of a Stack data structure to store String object. Stack A = new Stack(); Stack B = new Stack (); Stack C = new Stack(); A.push("1"); A.push("a".toUpperCase()); A.push("u".toUpperCase()); A.push("t"); A.push("x"); A.push("e".toUpperCase()); A.push("t"); //** while (!A.isEmpty()) { ***Structure-A String s A.pop(); System.out.print(s+ " "); switch (s.toLowerCase()) { case "a": case "e": case "i": case "O": case "u": B.push(s.toLowerCase()); break; default: } C.push(s.toUpperCase()); **********Structure-B **********Structure-C System.out.println(); while (!B.isEmpty()) { String s B.pop(); System.out.print (s+ " "); System.out.println(); while (!C.isEmpty()) { String s = C.pop(); System.out.print(s+ " "); (10 marks) c) Based on the following program segment, draw the representation of stack A, B and C after the execution of the line of codes as indicated by Structure-A1, Structure-B1, and Structure-C1 respectively.
