Question

Question: C#, Java or VB.Net

Given the following:

public static class PuzzleSolver
{
    public static string[] DICTIONARY = {"OX","CAT","TOY","AT","DOG","CATAPULT","T"};
    static bool IsWord(string testWord)
    {
        if (DICTIONARY.Contains(testWord))

            return true;

        return false;
    }
}

Now Implement the function public static int FindWords(char[,] puzzle), FindWords should return the number of all non-distinct occurrences of the words found in the array, horizontally, vertically or diagonally, and also the reverse in each direction.
