这题试了三种语言了

@liuenrui input() 会读入整行，

n=int(input())
a=int(input())

应改为

n,a= [int(i) for i in input().split()]

@liuenrui
帮你改了所有错误

t=int(input())
while t>0:
    n,a=map(int,input().split())
    r=1
    ans=0
    for i in range(1,n+1):
        r*=i
    while r>0:
        if r%10==a:
            ans+=1
        r//=10
    print(ans)
    t-=1
