What is the output of the following program?

StackPT stk1 = new ArrayStackPT( 8 );

StackPT stk2 = new ArrayStackPT( 8 );

StackPT stk3 = new ArrayStackPT( 8 );

StackPT stk4 = new ArrayStackPT( 8 );

QueuePT q1 = new ArrayQueuePT(8);

int n = 22;

while (n > 0){

stk1.push(n%2 + 1);

n = n/2;

}

String result = "";

while (!stk1.isEmpty()){

result += stk1.pop()+ " ";

}

System.out.println("the optput of stk1 : "+result); //___________

for(int i =0; i<8; i++)

stk3.push(i);

stk2.push(stk3.pop());

stk2.push(stk3.pop());

stk2.push(stk3.pop());

result = "";

while (!stk2.isEmpty()){

result += stk2.pop()+ " ";

}

System.out.println("the optput of stk2 : "+result); //___________

for(int i = 0; i < 8; i++)

{

if(i%4==0)

stk4.push(i+(int)stk3.pop());

}

result = "";

while (!stk4.isEmpty()){

result += stk4.pop()+ " ";

}

System.out.println("the optput of stk4 : "+result); //___________

int limit = 5;

for(int i = 0; i < limit; i++) {

q1.push((int)Math.pow(i, i));

}

result = "";

while (!q1.isEmpty()){

result += q1.pop()+ " ";

}

System.out.println("the optput of q1 : "+result); //___________

}

}
