Problem Description
Let A=∑ni=1ai∗10n−i(1≤ai≤9) (n is the number of A 's digits). We call A as “beautiful number” if and only if a[i]≥a[i+1] when 1≤i<n and a[i] mod a[j]=0 when 1≤i≤n,i<j≤n (Such as 931 is a "beautiful number" while 87 isn't).
Could you tell me the number of “beautiful number” in the interval[L,R] (including L and R)?
Could you tell me the number of “beautiful number” in the interval
Input
The fist line contains a single integer T (about 100), indicating the number of cases.
Each test case begins with two integersL,R(1≤L≤R≤109) .
Each test case begins with two integers
Output
For each case, output an integer means the number of “beautiful number”.
Sample Input
