How can the program recognize when there aren´t more inputs if use python3 ?
my program:
nums = [int(x) for x in input().split()]
nums.reverse()
for num in nums:
    print('{:.4f}'.format(num ** 0.5))

What's wrong? anyone can tell me ,pls

Consider 2 cases:
(1) K >= N
(2) K < N

and fry one side of each steak first.
Try cases like:
N=7,K=1; N=7,K=2; up to N=7,K=6 and find the pattern.

This is invalid test, but anyway

Use cumulative count of sorted values. int64_t is not needed (e.g.WA3).

I have done bs on overspeeding with upper bound of 1e12 and EPS of 1e-9.
Any idea?

Can you send to me some test????????))

my idea:

 sum( (-1)^m *  a^(n/(p[k1]*p[k2]*..*p[km] ) ) ), where p[i] - is prime number and n % p[i] == 0.

Domain and name must consist only of LOWERCASE letters and dots

The length of each crystal's side is L, not one.

Unfortunately, I can't write the Python solution due to the rules, but it exists! Try to find it!

input:
-2 -2 2 -2 2 2 -2 2
0 2 1
0 -3
output:
7.236067977

input:
1 0 0 1 -1 0 0 -1
0 0 1
2 -1
output:
1.236067977

 ... airplane must climb to an altitude of h meters during the first t seconds of the flight ...
Can time be less than t when height h is attained ?

10000

1 6

              1    2    3
1->2:180     180 -180
1->3:180     180      -180
2->3:180          180 -180
overall:     360   0  -360
prefix sum:  360  360   0

hence max from 1 to 3 is 360
do this similarly from 3 to 1

f(x) = (x-7)^2 + (x-4)^2 + (x-5)^2
Find x such that f(x) (cost function) is a minimum.

df/dx = 2(x-7) + 2(x-4) + 2(x-5) = 0
3x = 7+4+5
x = (7+4+5)/3

The biggest hurdle is the problem statement itself!

i think my algo is right but i have problem with overflow in C++.
who can give me good test?

PS: on Pypy i have TL50 using the same algo( And it's very strange because on test

my algo works <300ms




PS: AC in C++ after many hacking with overflow. I hate this problem because spent a lot of time to fix problem with arighmetic (not algo)
