Let f(x) be the number of 1's in the binary representation of x.

We can define f^k(x) as f(x) for k = 1, and f^(k-1)(f(x)) for k > 1.

Let f^*(x) be the smallest k >= 1 such that f^k(x) = 1.

Given N and K, how many numbers x between 1 and N inclusive have f^*(x) = K ?

Input :
The first line contains the number of test cases T. Each of the next T lines contains two space seperated numbers N and K.

Output :
Output one line corresponding to each test case, containing the answer for the corresponding test case. Output all answers modulo 1000000007.

Sample Input :
6
1 1
2 1
3 1
3 2
13 3
20 2

Sample Output :
1
2
2
1
3
10

Constraints :
1 <= T <= 1000
1 <= N <= 10^500
1 <= K <= 10
