( 9850 ) G D-Function PROGRAMMING bitmasks combinatorics math number theory

B'Let D(n) represent the sum of digits of n . For how many integers n where 10^{l} <= q n < 10^{r} satisfy D(k cdot n) = k cdot D(n) ? Output the answer modulo 10^9+7 . The first line contains an integer t ( 1 <= q t <= q 10^4 ) xe2 x80 x93 the number of test cases. Each test case contains three integers l , r , and k ( 0 <= q l < r <= q 10^9 , 1 <= q k <= q 10^9 ). For each test case, output an integer, the answer, modulo 10^9 + 7 . For the first test case, the only values of n that satisfy the condition are 1 and 2 . For the second test case, the only values of n that satisfy the condition are 1 , 10 , and 11 . For the third test case, all values of n between 10 inclusive and 100 exclusive satisfy the condition.
