Discuss the differences between a queue and a stack.

What will be an ideal response?


(a) A stack is a last-in/first-out (LIFO) data structure. Items are removed in the reverse order in
which they were inserted. A queue is a first-in/first-out (FIFO) data structure. It mimics a line.
Items are inserted at the end of the structure and are removed from the front of the structure.

A: double sum = 0; for (int i = 1; i <= 99; i++) { sum = i / (i + 1); } System.out.println("Sum is " + sum); B: double sum = 0; for (int i = 1; i < 99; i++) { sum += i / (i + 1); } System.out.println("Sum is " + sum); C: double sum = 0; for (int i = 1; i <= 99; i++) { sum += 1.0 * i / (i + 1); } System.out.println("Sum is " + sum); D: double sum = 0; for (int i = 1; i <= 99; i++) { sum += i / (i + 1.0); } System.out.println("Sum is " + sum); E: double sum = 0; for (int i = 1; i < 99; i++) { sum += i / (i + 1.0); } System.out.println("Sum is " + sum); a.
