[ICPC 2017 Urumqi R] Count Numbers
Problem Description
Now Alice wants to sum up all integers whose digit sum is exactly .
However we all know the number of this kind of integers are unlimited. So she decides to sum up all these numbers
whose each digit is non-zero.
Since the answer could be large, she only needs the remainder when the answer divided by a given integer .
Input Format
The input has several test cases and the first line contains the integer which is the number of test cases.
For each test case, a line consisting of three integers and describes the restriction of the digit sum and the given integer .
Output Format
For each test case, output a line with the required answer.
Here we provide an explanation of the following sample output. All integers satisfying the restriction in the input are and . The sum of them all is and that is exactly the sample output.
