In java

(a) Write a recursive method

public static long binomialCoefficientRecursive(int n, int k)

that computes the binomial coefficient C(n, k) according to the following formula:

Using your method, find the values of:

(i) C(30, 15), (ii) C(40, 20), (iii) C(50, 25)

Value is: 155,117,520 Value is: 137,846,528,820 Value is: 126,410,606,437,752

Are you getting a StackOverflow error / long computation times?

(b) Now write an iterative method

public static long binomialCoefficientIterative(int n, int k)

for finding the value of binomial coefficient using the following formula:

C(n, k) = * * * *

Using this method, find the values of:

(i) C(30, 15), (ii) C(40, 20), (iii) C(50, 25)

What can you conclude using both versions?
