I am getting error on test 27

n = int(input())
if 0 <= n <= 100:
    s1 = input().split()
    s2 = input().split()
    s1.extend(s2)
    uniques = set(map(int, s1))
    sorted_uniques = sorted(uniques)
    if 0 in uniques:
        if sorted_uniques == list(range(0, n + 1)):
            print("I become the guy.")
        else:
            print("Oh, my keyboard!")
    else:
        if sorted_uniques == list(range(1, n + 1)):
            print("I become the guy.")
        else:
            print("Oh, my keyboard!")
else:
    print("Oh, my keyboard!")

Test 27 is :

1 2

Read the prompt carefully and make sure you understand the input format

you are not parsing the input correctly

[tawny oracle]

??

parsing means

[hidden aspen]

your code assumes that little X is capable of passing levels 1 and 2
and little Y is capable of passing levels 2 and 3

i.e. together they can pass 1, 2, and 3

[tawny oracle]

yes

[hidden aspen]

this is not true - that isn't what the input means

[tawny oracle]

isnt that true

[hidden aspen]

that is not the intended interpretation of the input

i.e. you're pasing the input incorrectly

this is the part you're doing wrong

[tawny oracle]

3
1 2
2 2 3
Which means X can do 1,2 and Y can do 2, 3, ie together than can do 1,2,3

[hidden aspen]

nope

[tawny oracle]

Ohh

Indices of the levels X can pass

but still

0, 1 level and 2, 3 level

i still dont understand what is wrong

[hidden aspen]

read carefully

X cannot pass level 1

3
1 2
2 2 3

X can pass level 2
Y can pass levels 2 and 3
together they can pass levels 2 and 3
they cannot pass level 1

[tawny oracle]

omg oh i got it now

1 means the number of levels X can pass

[hidden aspen]

yes

[tawny oracle]

Not the fact that X can pass level 1

Oh thnxx @hidden aspen

should i close the ticket

?

[hidden aspen]

same for the third line for Y

[hidden aspen]

no problem

[tawny oracle]

Yeah

[hidden aspen]

sure

[tawny oracle]

!close
