Hey everyone, let's come straight to the point. To get past the initial phase whereby you aren't able to solve the problem of type Div3A, there can be 2 types of situations over here.

1. You might be lacking the required concepts like arrays, strings and for that I don't think you need any advise rather go and get those concepts in your brain.

2. If you have studied the basic concepts and yet are not able to solve the problems you can try this method. Take pen and paper and try to solve the problem yourself i.e. basically forget about programming and talk about how you will approach this mathematical/logical problem. The logic which you developed, code it! pretty simple.
