import re
t = int(input())
while t:
    s = input()
    s1 = re.split(' ', s)
    n = int(s1[0])
    m = int(s1[1])
    x = 1
    ans = 0
    while n:
        x *= n
        n -= 1
    x = str(x)
    l = len(x)
    for i in range(l):
        if(int(x[i]) == m) :
            ans+=1
    print(ans)
    t -= 1

@爱吃肉的瓶子 这题其实可以不动用Python的

€€£:C++允许STL!

P党:WTF?

€€£:允许Python3!

C党,P党:WTF?

@dead_X 不允许stl也可以把stl代码贴过去啊...没什么区别吧

@dead_X
太真实了吧...... 好习惯是先拿c++ AC一遍再py 3

@dead_X

€€£:Python3与其他语言时限一样!

Python党:WTF?

@SSerxhs 请注意他说的是只能使用某些头文件

by SSerxhs @ 2019-02-17 12:20:27

@jyttoby 没错啊，但是本地一般都有stl源码啊，贴过去不就好了

by jyttoby @ 2019-02-17 13:19:11

@SSerxhs stl源码里面别的头文件更多

（除非你有时间dfs出来最底层的）
