Beautiful Sequence

250 POINTS A sequence of l integers b1, b2, ..., bl (1 ≤ b1 ≤ b2 ≤ ... ≤ bl ≤ n) is called good if each number divides (without a remainder) the next number in the sequence. More formally for all i (1 ≤ i ≤ l - 1). Given n and k find the number of good sequences of length k. As the answer can be rather large print it modulo 1000000007 (10^9 + 7). Input The first line of input contains two sp
