python: invalid type hint in default code

def find_4_numbers(n: int) -> list[int, int, int, int]:

you're looking for a tuple, a list doesn't include its length in its type

a2 + b2 + c2 + d2 = n and a >= b >= c >= d > 0
...Perhaps there are a lot of valid results, please choose the one which has largest a...

The following basic test case in Python would contradict the description.

test.assert_equals(find_4_numbers(110), [9, 4, 3, 2])

While [9,4,3,2] is a solution: 110 = 81 + 16 + 9 + 4 110 = 9^2 + 4^2 + 3^2 + 2^2

The solution with the largest a-value is [10,3,1,0]: 110 = 100 + 9 + 1 + 0 110 = 10^2 + 3^2 + 1^ + 0^2

Python, probably others: add e.g. this fixed test case 435602 --> [659, 36, 4, 3]

Some solutions find [660, 0, 1, 1] instead, where a >= b >= c >= d > 0 is not true

good job myjinxin2015

Python translation

D translation

• Rust translation
• Go translation

the characteristics of the tests should be given in the description (number of tests and upper bound)

please choose the one which has largest a or largest b(if the value of a are the same) or largest c(if the value of a,b are the same)

Could someone translate this to proper english? I just cannot figure out the meaning... :/

There is an error in the tests for JS.

C# Translation ready for review.

COBOL translation.

JS: the test cases are a mess, full of unused stuff. Needs to be cleaned.

Once again, incredible Kata from @myjinxin2015!

Great. Short & clear description it is a good motivation to solve the kata :)
