error! round with '-' or don't?

e.t.

in JavaScript how can I get the string with IP?

for the same to me!
i'm disappointment!!

oh, thank U my dear friend)) I passed the kata!

all tests are past. exept:
in c# if word = "k"
Expected: 0
But was: 1

Why?

I'm sorry, but I have written above,
all are used from "Integer triangles with one angle equal to twice another".
but in python "Process was terminated"... at perimeter = 10488.
maybe, I use two loops in vain?

for n_=1500
"Process was terminated. It took longer than 6000ms to complete"

surely, here is the deep mathematics... we need Hint!
from wiki "Integer triangles" I use:
1.a = nn, b = mn, c = mm - nn and p = a+b+c => n = p/m-m (m in loop)
2.condition A=2B: a*(a+c) == b*b
3.number of integer triangles: p^2/48 or (p-3)^2/48
...and stop in surmising

it's strange! something is wrong...
if I have triangle: [30, [(8, 10, 12)]] - what are angles?
A = 41,41; B = 55.77; C = 82.82
C = 2*A
but in your cases there is no this triangle as per_ang_twice(3) = [30, [(8, 10, 12)]]
...and so on [45, [(12, 15, 18)]]...

i think, here is needed to explain more and more.
i can't find Name: "codevars"-string, "randomtests"-string... in "this".
where are that strings to find Message for??

to tiriana!
here is the problem with testing (Python).
I submit five times in a row, but every time in different test there is:
ValueError: The scale has been broken.

thank's!
we are waiting for)

Java
Almost all tests were passed. But in last random tests are problem..
[W, E, N, W, E, W]
{E=2, W=3, N=1}
len_string=2 NW
len_array=2 [N, W]
array lengths differed, expected.length=2 actual.length=1

expect, in tests there are some mistakes
[W, N, W, N, W, E, N, N, N, N, N, S, N, S, W, S, N, N, E, W, W, W, E, N, N, E, E, N, N, S, N, W, N, W, N, S, E, N, W, E, E, W, N, S, N, W, S, E, E, W, E, S, E, N, E, N, N, E, S, S, E, E, S, S, N, S, N, E, E, W, N, S, E, W, W, N]
{S=14, E=19, W=16, N=27}
NNNNNNNNNNNNNEEE
len=16 [N, N, N, N, N, N, N, N, N, N, N, N, N, E, E, E]

Thank U for your tasks!!
I's rather fun solving and useful!
