Kata

python new test framework is required. updated in this fork

How can we get to 1000 in this test case using only integers?

range1 = [1, 50]
range2 = [1, 50]
hMax = 1000
k = 5
test.assert_equals(max_val_f(range1, range2, hMax, k), [784.0, 841.0, 900.0, 961.0, 1000.0])

Description could use some KaTeX: https://docs.codewars.com/references/markdown/extensions#math-typesetting

( Haskell, possibly others )

The function should output the largest values of f(x, y) less or equal than hMax ..

That would be ".. the largest unique values .." ( or maybe "different" ).

I'm trying to solve this Kata in C#. I implemented a solution, which passes the sample tests, but fails the RandomTests. I get values for hMax, which are way bigger than the highest values, I get. And my values seem to go higher, than the expected solutions. Here is an example:

range1: 3 : 12 range2: 2 : 11 hMax: 7409283 k: 5

Expected string length 25 but was 28. Strings differ at index 1. Expected: "[243, 256, 343, 625, 729]" But was: "[625, 729, 1024, 1296, 2187]" ------------^

It seems, that hMax, which I receive, is much higher, than the one with which the test case computes its expected results. Could you check this?

Approved

I suggest changing "smaller than" to "not exceeding" here:

The function should output the largest values of f(x, y) smaller than hMax

This would make it more clear that hMax is allowed. It should have the meaning of "less than or equal to" or "not greater than".

Spelling error in the description: "bellow" should be "below" in the description of parameter #3.

The graph and its caption in the description use zmax and zMax. However, the definition of f, most of the description, and the solution/test template use h and hMax for the third variable.

For range1 and range2, the description states that the boundaries are inclusive. However, for the first test in the"Your Tests" section, I need to exclude the upper boundaries to pass the test. However, when I submit, I need to include the upper boundary to pass. For the second test, I get values that are higher. For example, for x = 18, y = 20, f(x, y) = 361, but this value is not included among the values in the expected result.
