Reverse a stack

#1

void reversestack(stack &s1){

int n = s1.size() ;
stack <int> s2 ;

while(n--)
 {
	int x = s1.top();
	s1.pop();
	
	while(s1.size()){

		s2.push(s1.top());
		s1.pop();
	}

	s1.push(x);
	
	while(s2.size()){
		s1.push(s2.top());
		s2.pop();
	}
}

}

why this code doesn’t give the desired output of reversing a stack?
