Is it right that p is divisor of n? If not, Can you write example?

I think, this should be renamed to "Cipher Message 4"

UPD: i have find mistake

PLEASE!!!!

Input in the task looks like:
13 14.1

Not like:
13
14.1

So change input in your program to
p,q=map(float, input().split())

0.046 - O(p) solution.
0.468 - O(p^2) solution, please add more tests.
UPD: understood, that there is cant be NO SOLUTION. But you can enlarge p.

this is my code
a=int(input())
b = [int(a) for a in input().split()]
c=int(input())
d = [int(c) for c in input().split()]
e=int(input())
f=[int(e) for e in input().split()]
spisok=b+d+f
spisok.sort()
kolich=0
for i in range(0, len(spisok)-1):
    if spisok[i-1]==spisok[i] and spisok[i]==spisok[i+1]:
        kolich+=1
print(kolich)

i dont know why but it writes wrong answer on test №37
please could you text me what is on this test

It says, that K is an amount of stones BETWEEN other stones. Why does Test4 answer equal n-1. I suppose it should be n-2, shouldn't it?

0) AC solve is DP on tree.
1) In DP inf = 1e9.
2) All test in the forum:

ans = 21

no matter who plays first and which sign is between numbers

5
5 4 3 2 1
(2)

1
1
(1)

10
3 3 4 2 5 6 1 9 9 3
(4)

you should output edges in input order

a,b = map(int,input().split())
if (a % 2 == 0 and b % 2 != 0):
    print("yes")
else:
    print("no")

Check that you use only shortest routes.
I don't have any tests, but when I started checking this, then I got ACC.

Таким образом, если для данного перекрёстка нет подразделений СКБ Контур находящихся ближе, чем в 6 кварталах, то мы обозначим его числом 0.
Carefully read this part of text.

Try n = 100000 and remember that 1e6 * 1e6 > 2e9.

The most important thing is that you shouldn't keep finding sets when you've already found 10,000.
Then you can optimize a little simple search and you get ACC.
Good luck!
