You are given an integer $$$n$$$. You have to apply $$$m$$$ operations to it.In a single operation, you must replace every digit $$$d$$$ of the number with the decimal representation of integer $$$d + 1$$$. For example, $$$1912$$$ becomes $$$21023$$$ after applying the operation once.You have to find the length of $$$n$$$ after applying $$$m$$$ operations. Since the answer can be very large, print it modulo $$$10^9+7$$$.
For the first test, $$$1912$$$ becomes $$$21023$$$ after $$$1$$$ operation which is of length $$$5$$$.For the second test, $$$5$$$ becomes $$$21$$$ after $$$6$$$ operations which is of length $$$2$$$.For the third test, $$$999$$$ becomes $$$101010$$$ after $$$1$$$ operation which is of length $$$6$$$.For the fourth test, $$$88$$$ becomes $$$1010$$$ after $$$2$$$ operations which is of length $$$4$$$.
The first line contains a single integer $$$t$$$ ($$$1 \le t \le 2 \cdot 10^5$$$) — the number of test cases.The only line of each test case contains two integers $$$n$$$ ($$$1 \le n \le 10^9$$$) and $$$m$$$ ($$$1 \le m \le 2 \cdot 10^5$$$) — the initial number and the number of operations. 
For each test case output the length of the resulting number modulo $$$10^9+7$$$.
