Problem: Panda has become a scientist recently. In his laboratory, there are infinite number of chambers where a chamber number K is connected to a chamber number K-1.  

The numbering of chambers start from 0. Initially, X number of particles are present in the chamber number 0. The number of particles present in chamber K is K times the number of particles present in chamber K-1.   You are supposed to help Panda in finding out the number of particles in a given chamber number N.  

Note: The number of particles in chamber K cannot be calculated until the number of particles in chamber K-1 are calculated.  

Input Format:

The first line will contain the integer T, the number of test cases. Each test case consists of two space separated integers N and X.   

Output Format:

For each test case, output the answer to Panda's query. Since the output can be very large, output the answer modulo 10^6+3.  

Constraints:

1 ≤ T ≤ 10^5

Subtask 1: (20 points)
1 ≤ N, X ≤ 10^5

Subtask 2: (80 points)
1 ≤ N, X ≤ 10^18SAMPLE INPUT

Explanation

Case 1: For first test case, initially there were 3 particles. 
In Chamber K=1, the number of particles became 1*3 = 3.

Case 2: Initially, there is only 1 particle.
In Chamber K=1, the number of particle became 1*1 = 1.
In Chamber K=2, the number of particle became 2*1 = 2.

Solution (in PYTHON):

Solution:
mx,mod= 10**6+13, 10**6+3
arr= [0]*mx
arr[0]=1
for i in range(1,mx):
    arr[i]= i* arr[i-1]
    arr[i]%=mod

for _ in range(input()):
    n,x= map(int,raw_input().split())
    if n> mx:
        print 0
    else:
        arr[n]%=mod
        cal= arr[n]*x
        cal%=mod
        print cal
