standard outputLet *S*(*n*) denote the number that represents the digits of *n* in sorted order. For example, *S*(1) = 1, *S*(5) = 5, *S*(50394) = 3459, *S*(353535) = 333555.

Given a number *X*, compute modulo 10^{9} + 7.

Input

The first line of input will contain the integer *X* (1 ≤ *X* ≤ 10^{700}).

Output

Print a single integer, the answer to the question.
