Java direct Recursion

[mark jacob]

I want to convert this mutual recursion prog into direct recursion. Any Help how to do this

class Arec {

int a;
int b;
static long h(int k)
{ a++;
if (k == 0) return 0;
else return h(k - 1) + i(k - 1);
}

static long i(int k)
{ b++;
if (k == 0) return 1;
else return h(k) * i(k - 1);
}


public static void main(String argv[])
{ int k;
for (k = 0; k< 4; k++)
{ a = 0;
b = 0;
System.out.println("\n h("+k+") = "+h(k)+", i("+k+") = "+i(k));

}
}

}
