OP solved it, closing

Input range should be specified: there can be potential performance requirements, but it is not clear whether it exists based on what's given.

and an array with floating-point numbers

No, that's a horrendous idea. Everyone in every competitive coding site will have a problem with you if you do this.

I think, at this moment only integers is correct input. I`ll add a test case for negative numbers

I suggest including additional test cases, such as an empty array, an array containing negative numbers, and an array with floating-point numbers. Alternatively, you could explicitly mention in the description that these types of inputs are not permitted.

Input: 2,8,4: expected true to equal false

Can you adwise some articles or, maybe, books to read about ways to implement this algorithm?

Nice work on the random tests.. great Kata :)

If a direction (left, right, up, or down) has a "T" at the end, it means you're supposed to move in that direction and then add the letter you land on to the password. If it's not there, you move but don't add to the password.

Can yoг explain in simle words - what is left(top etc) and leftT(topT etc) in this cata?

In random cases :

• a new HallOfFame is created with size and players arguments. eg xxx = new HallOfFame(3,[["ZZ",12],["xxx",9],["YyY",13]])
  Then size of its length is tested (should be equal to 'size' )
• then a list of players is added on after another, and each time a new player is added, the list of the tested Hall is compared to expected list
  (ie list of same size but with only avaible players, sorted as required)

Does it help ?

Ah you caught my trick!

Thanks for the help though
