Using switch statement, write a menu-driven program for the following : 

(i) To find and display the sum of the series given below :
S = x¹ -x² + x² – x⁴ + x⁵ – x²⁰ 
(where x = 2)
(ii) To display the following series :

{   if(m%3==0)
   break;
else
if(m%5==0)
System.out.println(m);
continue;
}

void paws(int a, int b) 
{ a = a + b; 
  b = a - b; 
  a = a - b;' 
System.out.println(a + "," + b); 
}
