#ADASUM. Ada and Expenses

Ada and Expenses

Ada the Ladybug has just returned from her trips. She noted all her expenses. Sadly, she only had a small piece of paper so she had to keep it in a compressed form. The compressed form is just a very long number. To restore the expenses, simply sum all contiguous subsequences of the number. Since this number might be pretty big, you only have to output it modulo 109+7 (1000000007).

Can you help her to restore the number?

Input

The first and the only line of input contains the compressed sequence of digits ([0..9]): 1 ≤ |s| ≤ 2*106
