KLVASCIS - Salama’s Birthday
It's a wonderful day, today is Salama's 20th birthday.
Being joyful and triumphant, every year he gains the love of the people. He noticed that each year the number of friends ti he makes increases by a factor r, while in his first year he made a friends. (a = r-1)
The number of friends he makes in the ith year is a ri-1.
It's commonly known that Salama loves math. Help him calculate Sn (the number of friends he will make in his first n years) modulo 1000003 (106 + 3).
Sn = a + a r + a r2 + a r3 + .... + a rn-1
Note:
X modulo Y (X%Y) is the remainder of dividing X by Y.
Input
Your program will be tested on one or more test cases. The first line of input will be a single integer T,
The number of test cases (1<=T<=20).Followed by T lines, each line consists of three integers a, r and n.
a = r-1
1 < r < 10
0 < n < 106 (May he live long and happily!)
Output
For each test case, print “Case_#i:_X” where “X” is your answer modulo 1000003(106 +3), “i” is the number of the test case (starting with 1) and “_” is a white space. Each output should be printed in a separate line.
Example
Input:
3
1 2 1
8 9 3
2 3 2 Output:
Case #1: 1
Case #2: 728
Case #3: 8
