Obligation:
need to prove termination of the following program:
package ConvertRec;

public class ConvertRec {

  public static int convert(List xs, int b) {
    if (xs == null) return 0;
    if (xs.value <= 0) return  b * convert(xs.next, b);
    return 1 + convert(new List(xs.value - 1, xs.next), b);
  }

  public static void main(String[] args) {
    Random.args = args;

    List xs = createList(Random.random());

    convert(xs, Random.random());
  }

  public static List createList(int l) {
	if (l <= 0) {
		return null;
	} else {
		return new List(Random.random(), createList(l-1));
	}
  }
}


package ConvertRec;

public class List {

  int value;
  List next;
