Stack s - new Stack();
s. push(10);
s. push(20);
s. push(30);
s. push(40);
// stack created with elements- 10 20 30 40

sum(s);

public static void sum(stack s){
Integer sum = 0;
stack tmp = new Stack();
// move the stack to new stack, it will be in reverse orde
// simultaneously sum the elements
while (Is.isEmpty())(
tmp.push(s.pop();
sum t tmp.peek();

sum t= tmp.peek ();

// move to original stack
while (Itmp.isEmpty()){
s.push(tmp.pop());
system.out.println("sum= "+sum.tostring());
OUTPUT-
10 pushed into stack
20 pushed into stack
30 pushed into stack
40 pushed into stack
40 pushed into stack
30 pushed into stack
20 pushed into stack
10 pushed into stack
10 pushed into stack
20 pushed into stack
30 pushed into stack
40 pushed into stack
Sum= 100
Sum of 10, 2O, 30, 40 = 100
I hope it helps. For any doubt, feel free to ask in
