This applications is developed in the context of my Postdoctoral interview with Queen's University. It is written in Java and in order to execute it type:
$ javac wordSearch.java
and
$ java wordSearch <wordToSearchFor>
Note that the applications can accepted both lower or upper case letter as a command-line option. An array of letters is give by default (found in the root direcotry of this folder i.e., array2D.txt). However, if you wish to use a different one just pass the path of the new file as the second command line argument. To add your own array execute as follows:
$ java wordSearch <wordToSearchFor> <../my/own/pc/path/and/the/file.txt>
