Let us define two functions *f* and *g* on positive integer numbers.

You need to process *Q* queries. In each query, you will be given three integers *l*, *r* and *k*. You need to print the number of integers *x* between *l* and *r* inclusive, such that *g*(*x*) = *k*.
The first line of the input contains an integer *Q* (1 ≤ *Q* ≤ 2 × 10<sup class="upper-index">5</sup>) representing the number of queries. 

*Q* lines follow, each of which contains 3 integers *l*, *r* and *k* (1 ≤ *l* ≤ *r* ≤ 10<sup class="upper-index">6</sup>, 1 ≤ *k* ≤ 9).
In the first example:
 -  *g*(33) = 9 as *g*(33) = *g*(3 × 3) = *g*(9) = 9 -  *g*(47) = *g*(48) = *g*(60) = *g*(61) = 6 -  There are no such integers between 47 and 55. -  *g*(4) = *g*(14) = *g*(22) = *g*(27) = *g*(39) = *g*(40) = *g*(41) = *g*(58) = 4
