Hi, @Eldoir

I’ve 2 problems :

  • The first test where the answers are 14.9 and 14.9 => With my code I found 14.9 and 14.4 !! Strange because all other tests are ok ?

  • Second , on submission I don’t pass the “Winter is coming” test ? Is there something special with that one ?

Thanks

Philippe

Hi @PhilippeBordmann,
For your first point, since you talk about the “test”, then you know the inputs: it’s probably your solution that isn’t 100% right?
For your second point, I guess you talk about the “validator” because you say “on submission”: then you don’t know the inputs, and I understand how frustrating it is.
If I were you, I would first try to pass all the tests before questioning the validators: you probably got something wrong with your solution.
You can pm me if you want to show me your solution, and maybe I’ll be able to give you a hint about what’s wrong.
Thanks! :slight_smile:

Hi,
No i didn’t see it, sorry!
I answer you right now. :slight_smile:

I found the sames values… do you know what is wrong with 14.4 ?
thx

#7

The value in the second line (in this case 14.9) is calculated like this:

  • You add all integers, you get (except the last one, if the number of integers is odd) -> 8+8+6+3+2+4+8+6+9+5+2+1+5+2+8+8+3+3+6+7+2+8+1+7+4+5+4+2+3+9 = 149
  • You divide the sum by the half number of the values you get -> you get 30 values: 149/15 = 9.933333…
  • You add 5: 9.933333… + 5 = 14.933333…
  • You round it to one decimal place: 14.9

I hope this helps you finding the bug in your program.
If it doesn’t, you can send me a private message with your code, then I can help you better.

I can pass all validators but i got stuck at an hour in summer validator(number 5).
I think my code is perfect as per the statement and conditions given in the problem.
It passes all the test cases successfully
Below i have posted my code

import statistics as stats

mean=stats.mean

l=[]

f1=[]

f2=[]

for i in range(int(input())):

    x=list(map(int,input().split()))

    f1.append(10+(sum(x)-40)/7)

    l+=[j for j in x]

x=round(mean(f1),1)

print(x)

if 5<=x<=32:

    x=len(l)

    if x%2!=0:x-=1  #reducing length for odd case

    for i in range(0,x,2):

        f2+=[sum(l[i:i+2])+5]

    print(float(round(mean(f2),1)))

please help this problem has really a lot of time given that all we need to do is find 2 averages…:frowning:

This is your bug, the description says “this is fairly accurate between 5 and 30°C”.

Hi @everyone,

As many users here, it seems i’m stuck while submitting my code… validators may not pass i guess … but i really don’t figure it out since we 're not aware of inputs…
Can anyone help me please ?

Regards

#13

Could you specify your problem?
What are the validators, your program is failing at?
Could you share parts of your program?

#14

Hi,

Winter is comming validator is not passing while test is OK.

I send you my code in private message :slightly_smiling_face:

Thank you in advance

Select expert mode in option, add this custom validator and show us what it returns:

2
1 0 1 1 0 0 1 0 1 1 1 1 1 1 1
0 1 0 1 1 1 0 1 0 1 0 0 0 0 1

#17

Well itsAFeature solved my issue in private messages (due to code sharing)

It seems that i migth know how to javascript a bit but i don’t know how to read lol

I messed up this
Original text:

On the second line , if the result on the first line is between 5 and 30 (inclusive), then return the average of the estimates calculated every 8

What i understood:

On the second line , if the result of N8 is between 5 and 30 (inclusive), then return TCN8

lol i would have figure it out for a while alone, thank you all
