--description--

Given a 2D array representing a map of the ocean floor that includes a hidden treasure, and an array with the coordinates ([row, column]) for the next dive of your treasure search, return "Empty", "Found", or "Recovered" using the following rules:

• The given 2D array will contain exactly one unrecovered treasure, which will occupy multiple cells.

• Each cell in the 2D array will contain one of the following values:

  • "-": No treasure.
  • "O": A part of the treasure that has not been found.
  • "X": A part of the treasure that has already been found.

• If the dive location has no treasure, return "Empty".

• If the dive location finds treasure, but at least one other part of the treasure remains unfound, return "Found".

• If the dive location finds the last unfound part of the treasure, return "Recovered".

For example, given:

[
  [ "-", "X"],
  [ "-", "X"],
  [ "-", "O"]
]

And [2, 1] for the coordinates of the dive location, return "Recovered" because the dive found the last unfound part of the treasure.

--hints--

dive([[ "-", "X"], [ "-", "X"], [ "-", "O"]], [2, 1]) should return "Recovered".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "X"], [ "-", "X"], [ "-", "O"]], [2, 1]), "Recovered")`)
}})

dive([[ "-", "X"], [ "-", "X"], [ "-", "O"]], [2, 0]) should return "Empty".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "X"], [ "-", "X"], [ "-", "O"]], [2, 0]), "Empty")`)
}})

dive([[ "-", "X"], [ "-", "O"], [ "-", "O"]], [1, 1]) should return "Found".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "X"], [ "-", "O"], [ "-", "O"]], [1, 1]), "Found")`)
}})

dive([[ "-", "-", "-"], [ "X", "O", "X"], [ "-", "-", "-"]], [1, 2]) should return "Found".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "-", "-"], [ "X", "O", "X"], [ "-", "-", "-"]], [1, 2]), "Found")`)
}})

dive([[ "-", "-", "-"], [ "-", "-", "-"], [ "O", "X", "X"]], [2, 0]) should return "Recovered".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "-", "-"], [ "-", "-", "-"], [ "O", "X", "X"]], [2, 0]), "Recovered")`)
}})

dive([[ "-", "-", "-"], [ "-", "-", "-"], [ "O", "X", "X"]], [1, 2]) should return "Empty".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(dive([[ "-", "-", "-"], [ "-", "-", "-"], [ "O", "X", "X"]], [1, 2]), "Empty")`)
}})
