Why the c++ tutorials are easy and the challenges are in another level & how can I read the challenges programs without dual

Question

Easy but not easy

Answer 1

//Yes, That's something our problem, like in college exam we think courses are easy and we get exam question from course we never read. It needs some times of practice and learning more to and play challenges more and you will get it easy

Answer 2

I recommend to treat the challenges as 'tutorial level 2'.

If you do them regularly and also write code yourself, you'll get a better feeling for them in a short time.
