Project Euler > Problem 169 > Exploring the number of different ways a number can be expressed as a sum of powers of 2. (Java Solution)

Problem:

Define f(0)=1 and f(n) to be the number of different ways n can be expressed as a sum of integer powers of 2 using each power no more than twice.

For example, f(10)=5 since there are five different ways to express 10:

1 + 1 + 8
1 + 1 + 4 + 4
1 + 1 + 2 + 2 + 4
2 + 4 + 4
2 + 8

What is f(1025)?

Solution:

171

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

public interface EulerSolution{

public String run();

}
