Is it possible for me to de-register from the contest on the Yandex system? I would like to enter as a team but accidentally joined as an individual.

      I joined as an individual by accident, so I was wondering how to de-register (I know how to register as a team). Thanks for your help though!

GNU c++ 11 (4.9) g++ -O2 -fno-stack-limit -std=c++0x -x c++ file -o executable_file executable_file

Shouldn't it be -std=c++11?

    G, at most one t_j will be not equal to the index of the largest number in a series.

    I guess you already have the following algo:

    1. Use N queries to find 1 bit sequence which gives N/2
    2. Use N queries to get the final answer

    Now in step 1, instead of using those N queries, use random 500 times.

      I know why I got failed.Before I just used o(n+n/2) rand() operations, now instead I use o(n/2*n) rand() operations and got AC.
