// --- Sample implementation for the task art ---

// To compile this program with the sample grader, place:
//     art.h art_sample.cpp sample_grader.cpp
// in a single folder, then open the terminal in this directory (right-click
// onto an empty spot in the directory, left click on "Open in terminal") and
// enter e.g.:
//     g++ -std=c++17 art_sample.cpp sample_grader.cpp
// in this folder. This will create a file a.out in the current directory which
// you can execute from the terminal as ./a.out See task statement or
// sample_grader.cpp for the input specification
