Apart from the Learn Java app, what books and internet resources would any helpful person on this forum suggest to a college freshman(me) taking intro to CS, and struggling? Right now, I'm struggling with writing my own for loops and nested for loops. I'm really confused. Usually, I'm very good coming up with solutions to analytical problems, but intro to CS is making me feel really dumb. I sincerely need help.
