Given a positive integer X, an X-factor chain of length m is a sequence of integers,
1 = X0, X1, X2, …, Xm = X
Xi < Xi+1 and Xi | Xi+1 where a | b means a perfectly divides into b.
Now we are interested in the maximum length of X-factor chains and the number of chains of such lengt
- The input consists of several test cases. Each contains a positive integer X (X ≤ 220).
- For each test case, output the maximum length and the number of such X-factors chains.
