Either or, I think

the clues are given as a 2d tuple (row_hints,col_hints)

This appears to be reversed when validating the solution

This is the way

I have also seen this! Even in my own katas.

retired

retired

Description:

Input: "Ab!"
[...]
Result: "abb!"

Tests:

test.assert_equals(decode_signal("Ab!"), "abbb!")

As far as I can see, the random tests do not conform to the given rule set.

for example input "nBVIHDQq" expects

'NNNNNNNNNNNNNNBBBBBBBBBBBBBBBBvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv... etc ...'

What accounts for all the B's if its position is 2 in the alphabet and index 1 in the input string?

Sample tests are borked:

undefined method 'count' for nil:NilClass (NoMethodError)

Added to description, fixed in tests. Thank you for feedback.

SyntaxError: Identifier 'HelpMe' has already been declared
    at Object.compileFunction (node:vm:360:18)

When running the sample tests.

const hills1 = [[10, 5], [5, 10], [8, 8]];

What do these numbers represent? There's no mention of how the data is passed to the constructor.

you're right

This was retired once before, and will be so again I suspect.

I love this lol

👍 It was pretty half-assed anyway :-)
