    Its most likely a scam. I dont think they are interested in actually paying people.

      a lot of people, both international and indians, have been involved in codechef setting before. Please do not make such wild accusations.

I gave div 2, the question A felt a bit harder than B and even C!

Div 3 B was a good question. I had this approach pruning the unnecessary 'b's out after 'a' to match it with regex b*(a(b*))* and then equating them, but took long time in implementing it.

    It's actually easier than that. Just make sure that the total number of a's and the number of initial b's are equal.

    Just make sure the number of a's in both are equal and if so then the first occurrence of a should be same, as we can't add more b else before that.
