Small explanation: First, I split the data into each line and cleared all null values (i.e. empty values). Then, using a for loop, I went through each line and split that into characters. Then, I looped through each character evaluating if it was a digit and the first digit I found I added to a temporary string and then used break to escape the first for loop. Then I started on the second where I did the same thing, but just backwards using the .reverse() method. Then, I added the number I found to total (having to parse it to an int before I can add it as it was a string beforehand)
