Ratings and reviews

one of the best DAS apps for visual learners! I've tried nearly every one and this is up there as one of the best. I think to have full access they ask less than 10 bucks. we'll worth it.

The app is really helpful to me, but there are some topics that I was looking for but couldn't find here, such as dictionary (closed and open), sets (bit vector, computer word), and virtual heap. If you could include them as well (this is actually from the C language). Can you also include the C language? Btw, I really need the dictionary... If it is possible, will you make another update on Tuesday, please🙏

only few basic structures and algorithms are accessible. They want money for copypasted texts. I would recommend books by Sedgwick or Lafore instead. This will be more efficient
