Project Euler > Problem 181 > Investigating in how many ways objects of two different colours can be grouped. (Java Solution)


Having three black objects B and one white object W they can be grouped in 7 ways like this:

(BBBW) (B,BBW) (B,B,BW) (B,B,B,W) (B,BB,W) (BBB,W) (BB,BW)

In how many ways can sixty black objects B and forty white objects W be thus grouped?



The solution may include methods that will be found here: .

public interface EulerSolution{

public String run();
