I want to congratulate you guys for conducting a contest ! Well done and may you conduct many more contests in the future.

That being said, I absolutely need to say this — Problem B was absolutely terrible. I still have no idea what it means.

You guys followed a very good template for problems C, D and E. Statements were short, concise, clear and mathematical. Why not use it in B too ? I still have no idea what B means. When you are not able to communicate the question clearly, at least include an explanation of the test case :)

I enjoyed problems C, D and E :)

I couldn't complete D and E yet :). I'll work on it now.

I got TLE when I tried C with a segment tree but got AC when I used a Fenwick tree because of the smaller constant factor. I was just wondering if this was intentional ?

Very nice contest and I think I learnt a lot from it :)

P.S. — Here are my solutions to the contest and here is my editorial on C.
