And I don't think you need it that big

Any visual basic programming guru

How to improve problem solving skills

Any pre requirements for problem solving

Yep but Iam not getting idea how to solve the problem for some questions

How to start getting ideas

read this book "Introduction to algorithms" 3d edition this will give you the basic fundamentials of problem solving using standard algorithms/data structures

By not trying to get spoonfeeded and actually thinking

And is there any standard techniques for problem solving we should know

i need a expert in C/C++ for RSA implementation

doesnt specify many things: can I pick it from 1 box only? then split by color and take only from the red box, can I look at the box when I pick? then i dont care of the boxes and just take red ones

which is best compiler for c++
