Compression algorithms almost always have some form of space overhead, which means that they are only effective when compressing data which is sufficiently large that the overhead is smaller than the amount of saved space. Compressing a string which is only 20 characters long is not too easy, and it is not always possible. If … Read more

Your code starts the row and column at 1—which means you’re skipping the initialization of row/column 0. That’s probably where at least some of the problems are coming from, since you’re using your 5×5 array (rows/columns 0,1,2,3,4) as … Read more
