Show what is written by the following segment of code, given that item1, item2, and item3 are int variables, and stack is an object that fits our abstract description of a stack. Assume that you can store and retrieve variables of type int on stack. item1 = 1: item2 = 0: item3 = 4: stack.push(item2): stack.push(item1): stack.push(item1 + item3): item2 = stack.top(): stack.push (item3*item3): stack.push(item2): stack.push(3): item1 = stack.top(): stack.pop(): System.out.println(item1 +"" + item2 +"" + item3): while (!stack.isEmpty()) } item1 = stack.top(): stack. pop(): System.out.println(item1): }
