EulerianPath

java.lang.Object
- edu.princeton.cs.algs4.EulerianPath

```
public class EulerianPath
extends java.lang.Object
```
The EulerianPath class represents a data type for finding an Eulerian path in a graph. An Eulerian path is a path (not necessarily simple) that uses every edge in the graph exactly once.
This implementation uses a nonrecursive depth-first search. The constructor runs in O(E + V) time, and uses O(E + V) extra space, where E is the number of edges and V the number of vertices All other methods take O(1) time.
To compute Eulerian cycles in graphs, see EulerianCycle. To compute Eulerian cycles and paths in digraphs, see DirectedEulerianCycle and DirectedEulerianPath.
