SPATTERN - Subset Pattern |
You are given a number X. Let us define an array A. You have a sequence X^0, X^1, X^2, ..... Take 0 item, 1 item, 2 items, ...... per every time and sum them up. These sums are the elements of array A.
Sort A in increasing order. You are given a number n. You have to print the number in the n-th position. [0 - indexed]
For example, let x = 2. Then the array A = {0, 2^0, 2^1, 2^0 + 2^1, 2^2, .....} or A = {0,1,2,3,4, .....}.
Input
The input begins with the number t of test cases in a single line (t<=10^5). In each of the next t lines there are two numbers x and n (0 <= x, n <= 2^63) separated by a space.
Output
Just print the desired number in the n-th position of the array. As the number can very big; output the answer modulo 10000009.
Example
Input: 2 2 4
5 10
Output: 4
130
