This program will read a word search and a word dictionary from the provided files. Develop four methods: (1) A method to read the word search. (2) A method to read a dictionary of words, and (3) two methods to test the first two methods. The Method stubs are provided for you. (1) The first method, readDictionary will take as input a string that contains the name of the provided dictionary text file. The name of the text file provided is dictionary. txt. This method will return a list of the words found in the dictionary. txt file.
