test 4 ??? help me please

B)

Draw a polygon. the sum of its angles is pi*(n-2). The sum of pieces of circles is R*(n*pi-(n-2)*pi)=2*R*pi (you can see it easily if u draw)

sort the array. maintain W, the total weight of the array.
start from the smallest element and add A[i] * W to ANS.
subtract A[i] from W.
add A[i] * W again.

Is it the same problem if I placed containers in linear massive?

My algorithm passes all the tests I have designed, but still misses test 1. Can I get the input for this test ?

I would suggest you to think about sumulating all possible situations like dropping eggs from first floor, from second, from third ,..., from n-th and we must choose then worst case scenario, but try to minimize that result.

n=int(input())
print(math.ceil(n/(9*5)))
i=0
while(n>9):
    print(9,end='')
    n-=9
    i+=1
    if i%5==0:
        print(end=' ')
print(n)

test 3 ??? help me please

2 test. why?

I thought that using the sieve of Eratosthenes would slow down the program, but it turned out the opposite.

What is the output for this test?

I had MLE on test 33. I just changed int to short and 1,0 to bool
Sorry if this is too obvious
