My issue

Hi there I have solved this problem after running it on sample inputs it shows proper outputs but after submitting it, it is showing run-time error I am unable to find any error myself please help me with this…

My code

# cook your dish here
t = int(input())
for i in range(t):
    a,b = map(int,input().split())
    if a>b:
        if a-b>=10:
            print(0)
        elif a-b<10:
            if (b+10-a) < 3:
                print(1)
        else:
            print((b+10-a)//3)
    if a<b:
        if (b-a)<10 or (b-a)>10:
            print((b+10-a)//3)
        elif b-a == 10:
            print(b+10)//3
