1. No sample tests for Rust
2. No sample solution for Rust

Fixed. assert_eq!(actual, expected)

Only during the first call. The tests are always the same.
I've forked Rust Translation with real random tests.

https://github.com/Codewars/codewars.com/issues/556
Crate Random is available now.

No random tests for Rust.

Is done.

Now it works.

I've added the random tests. But rand methods not works on codewars. It's a draft now.

Sorry. My mistake.

Length of firstname is numbered from 0 in random tests.
But description says count from 1.
Length of PAUL is 4 not 3.
It's not a problem with sample tests. But a big problem with random tests.
Here small example.
st = "Matthew,John,Bob"
we = [16, 33, 70]
If length is numbered from 0.
John = 1683
Matthew = 1552
Bob = 1540
If length is numbered from 1.
John = 1716
Bob = 1610
Matthew = 1568

Best C# solutions calcs the score with length which numbered from 0.

1. I've changed the epsilon to 0.000001.
2. Random tests are currently impossible in Rust.

The length of the firstname is added to the sum of these ranks hence a number n.

PAUL -> n = length of firstname + 16 + 1 + 21 + 12 = 4 + 50 -> 54
length of firstname = 4 not 3

And random tests will fail (e.g. C#).
Because ranks are numbered from 0 in tests solution.
This contradicts to the condition.

Thank you.

Thank you

Sample tests have an issue in C#

MaxPossibleScore(new Dictionary<string, int> { {"a", 1} }, new string[] {}))
But string needs to change to object.

[Test]
public void FixedTests()
{
    Assert.AreEqual(1, Kata.MaxPossibleScore(new Dictionary<object, int> { { "a", 1 } }, new object[] { }));
    Assert.AreEqual(2, Kata.MaxPossibleScore(new Dictionary<object, int> { { "a", 1 } }, new object[] { "a" }));
    Assert.AreEqual(29, Kata.MaxPossibleScore(new Dictionary<object, int> { { "a", 1 }, { "b", 14 } }, new object[] { "b" }));
    Assert.AreEqual(14, Kata.MaxPossibleScore(new Dictionary<object, int> { { "a", 1 }, { "b", 2 }, { "c", 4 } }, new object[] { "a", "b", "c" }));
    Assert.AreEqual(23, Kata.MaxPossibleScore(new Dictionary<object, int> { { "a", 2 }, { "b", 5 }, { "c", 8 } }, new object[] { "c" }));
}
