Problem Statement

Given is a string S. Each character in S is either a digit (0, ..., 9) or ?.

Among the integers obtained by replacing each occurrence of ? with a digit, how many have a remainder of 5 when divided by 13? An integer may begin with 0.

Since the answer can be enormous, print the count modulo 10^9+7.

Constraints

S is a string consisting of digits (0, ..., 9) and ?.

1 \leq |S| \leq 10^5

Input

Input is given from Standard Input in the following format:

S

Output

Print the number of integers satisfying the condition, modulo 10^9+7.

Sample Input 1

??2??5

Sample Output 1

768

For example, 482305, 002865, and 972665 satisfy the condition.

Sample Input 2

?44

Sample Output 2

1

Only 044 satisfies the condition.

Sample Input 3

7?4

Sample Output 3

0

We may not be able to produce an integer satisfying the condition.

Sample Input 4

?6?42???8??2??06243????9??3???7258??5??7???????774????4?1??17???9?5?70???76???

Sample Output 4

Solution in Python (3.4.3) (judge verdict: Runtime Error)

s = list(input())

dp = [[0 for _ in range(13)] for _ in range(len(s))]
multi = 1
for i in range(10):
    if s[0] == '?':
        dp[0][i] = 1
    else:
        dp[0][int(s[0])] = 1
for i in range(1,len(s)):
    if s[i] == '?':
        for j in range(13):
            if dp[i-1][j] != 0:
                for k in range(10):
                    rest = (j*10+k)%13
                    dp[i][rest] += dp[i-1][j]
    else:
        for j in range(13):
            if dp[i-1][j] != 0:
                rest = (j*10+int(s[i]))%13
                dp[i][rest] += dp[i-1][j]
print(dp[i][5]%(10**9+7))
