DUKKAR  Dukkar and Pikka
Pika and Dukkar are roomie. Pika is a nerd and likes to play with mathematics! Pika's favourite topic is pascal triangle and he proclaims that he can solve any problem related to this. So Dukkar decides if it's really true!
Dukkar gives a number N and a prime number P. N is the Nth row of pascal triangle starting with 0. Dukkar asks Pika to find how many numbers in nth row are divisible by P. Since the number can be very large so, Pika has to write a program. Since end sem are coming and Pika has to top in his batch so he asks you for help. Can you help Pika?
Input
The first line of the test file will contain T (T < 100000) where T is the no. of test cases. Each of the next T lines will contain two integers N (0 <= N <= 10^{18}) and P (2 <= P <= 10^{5}) as defined above.
Output
For each test case print on each line K the number of numbers divisible by P on Nth row of the pascal triangle.
Example
Input: 2 2 2 7 7 Output: 1 6

Two entries in Row 13 are incorrect in the figure. They should be 286 instead of 186. BTW, nice problem.
