Code : https://paste.pythondiscord.com/LTWA

Stuck at test case 4

IR : Key error

[bitter cradle]

Do you have the full traceback/error?

[tepid pollen]

it's dmoj

so I can't see

[hot cape]

Is this a quiz?

[tepid pollen]

no

so if you have the answer

you can show me

but I would like to know the thinking tho

I need to train my logic

[hot cape]

Why not just run it in a python shell and get the output

[tepid pollen]

because I don't know the input

[hot cape]

Not sure how you are supposed to code a program when you don't know what the input should be

[tepid pollen]

do you use online judge to solve question?

[bitter cradle]

boy that's helpful

[tepid pollen]

alr

do you know what is wrong?

[bitter cradle]

It'll be really hard for us to determine this without knowing wha tthe input is

[tepid pollen]

any possible key error for my code?

like bugs and stuff

key error happen when the key is not found right?

[bitter cradle]

mmhmm

You're doing some funky stuff with the dictionary key here

    if not all(tiles_num[key] == 1 for key in tiles_num):
        for key in tiles_num.keys():
            if str(int(key) * 2) in tiles_num:
                tiles_num[str(int(key) * 2)] += int(tiles_num[key] / 2)
            elif str(int(key) * 2) not in tiles_num and str((int(tiles_num[key] / 2) * 2) * int(key)) not in tiles_num:
                num = is_power_of_two(int(tiles_num[key] / 2) * 2)
                if str(num * int(key)) in tiles_num:
                    tiles_num[str(num * int(key))] += 1
                else:
                    max_num = max(max_num, num * int(key))
            elif str((int(tiles_num[key] / 2) * 2) * int(key)) in tiles_num:
                tiles_num[str(tiles_num[key] * int(key))] += 1

My guess is it's somewhere in there

[tepid pollen]

I solve the key error

know I stuck at task 6

main difference

            elif str((int(tiles_num[key] / 2) * 2) * int(key)) in tiles_num:
                tiles_num[str((int(tiles_num[key] / 2) * 2) * int(key))] += 1

do you know why this doesn't work?
2 4 8 16
0 0 0 0
16 2 8 2
0 0 0 0
16

32 is the correct answer

but it output 16
