        I'm not sure how to put them together. How do I get the file into the array? I'm trying to use the i and j to put the information in to the array. The file is made up of user ids, item ids and the rating the user has for each item. The file starts like this: 1 1 1 881250949
        1 2 5 881250949
        1 4 2 881250949 ect...
