Given this set of interfaces:
public interface Processor<T,U> {
U process(T arg);
}
public interface Splitter<T,V> {
V[] split(T arg);
}
public interface Worker<V,W> {
W processPart(V part);
}
public interface Aggregator<U,W> {
U aggregate(W[] args);
}

and this scenario:
Please provide
1. An implementation of Processor interface
2. Test cases for testing the implementation
