    That's because your solution does not handle the specified kind of input. In input you have no numbers, the mountains are given literally as a map filled with ^. Look at the sampel tests, and the example input:

        char[][] mountain = {
      "^^^^^^        ".toCharArray(),
      " ^^^^^^^^     ".toCharArray(),
      "  ^^^^^^^     ".toCharArray(),
      "  ^^^^^       ".toCharArray(),
      "  ^^^^^^^^^^^ ".toCharArray(),
      "  ^^^^^^      ".toCharArray(),
      "  ^^^^        ".toCharArray()
    };      
    assertEquals(3, Dinglemouse.peakHeight(mountain));

    Your solution should handle a map of mountains and deduce the numbers.

    We don't know. We would have to see your code to know.
