Will you ever make the onsite contest page public? The public rankings don't tell how many users solved a particular problem.

    Actually, you can see that because the problems are given in a specific order in the rank list from left to right and that order is same for the mirror contest and the onsite contest. So, for Gwalior Regionals the problems code are:-

    P1 — ZUBWALLT

    P2 — QTRAGAIN

    P3 — TRICHEF

    P4 — OPTCODE

    P5 — COUPSYS

    P6 — KALADIN

    P7 — LIGHTARE

    P8 — TALESQUA

    P9 — TALETRI

    And this is true for all the regionals. So, you can just map the mirror contest rank list to the onsite rank list from left to right.

Hi,

In problem TALESQUA answer will always be integer? Then why do these two submissions give different verdict?

Submission 1 (AC)

Submission 2 (WA)

They only differ by line cout<<fixed<<setprecision(8)<<ans<<"\n";. I know in the question, it is written output a real number but integers are also real number. :3

    Don't print doubles using cout<<ans<<endl; Especially when their values can be large. For example, your program prints 9.9998e+09 as the answer. This leads to loss of precision.
