/*
SAMPLE GRADER for task ART

USAGE:
place together with your solution and art.h in the same directory, then open the terminal in this directory
(right-click onto an empty spot in the directory, left click on "Open in terminal") and enter:
    g++ <flags> sample_grader.cpp <solution_file>
e.g.:
    g++ -std=c++17 sample_grader.cpp art.cpp
This will create a file a.out in the current directory which you can execute from the terminal as ./a.out

INPUT/OUTPUT:
The sample grader first expects on standard input two lines. The first line should
contain the integer N. The second line should contain a list of N space-separated
integers, the correct ranking of the collections in the same format as for publish
and answer. Then, the grader calls solve(N) and writes to standard output a protocol
of all grader functions called by your program. Upon termination, it writes your
verdict to standard output.
