Project Euler > Problem 178 > Step Numbers (Java Solution)

Problem:

Consider the number 45656.
It can be seen that each pair of consecutive digits of 45656 has a difference of one.
A number for which every pair of consecutive digits has a difference of one is called a step number.
A pandigital number contains every decimal digit from 0 to 9 at least once.
How many pandigital step numbers less than 1040 are there?


Solution:

669171001

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

public interface EulerSolution{

public String run();

}
