Question 4 (10 marks)

We wish to compute the sum of all odd integers between n1 and n2. Note that n1 and n2 are either, both long integers or both big integers and n2 is always greater than n1.

Compare the design using 5 different methods. The following UML diagram shows the five different methods:

(a) The 1^st method, an iterative version, uses any type of loops and receives two long parameters

(b) The 2^nd method, uses the LongStream in Lambda and stream, receives two long parameters

(c) The 3^rd method, an iterative version, receives two BigInteger parameters and the return type is also a BigInteger

(d) The 4^th method, a recursive version, receives two parameters of long types with long return type.

(e) The 5^th method, a recursive version, receives two BigInteger parameters and the return type is also a BigInteger.

In the main method, generate two integers n1 and n2 make sure that n2 is greater than n1, invoke the 5 methods and display the results. Upon execution of your program, you will see the following sample output:

Question 4 (10 marks) We wish to compute the sum of all odd "integers" between n1 and n2. Note that n1 and n2 are either, both long integers or both "big" integers and n2 is always greater than n1. Compare the design using 5 different methods. The following UML diagram shows the five different methods: Supp_4 -static long sumOdd Mong n1, long n2) -static long sumOdd Llong n1, long n2) -static BigInteger sumOdd B(BigInteger n1, BigInteger n2) -static long sumOdd R(long n1, long n2) -static Biointeger sumOdd BR(BigInteger n1, BigInteger n2) + static void main(Stringl args) (a) The 1st method, an iterative version, uses any type of loops and receives two long parameters (b) The 2nd method, uses the LongStream in Lambda and stream, receives two long parameters () The 3rd method, an iterative version, receives two BigInteger parameters and the return type is also a BigInteger (d) The 4th method, a recursive version, receives two parameters of long types with long return type.
