[tip] chrono 이용하여 execution time 체크하기

#include <chrono>

auto start = std::chrono::high_resolution_clock::now();
auto stop = std::chrono::high_resolution_clock::now();
auto duration = std::chrono::duration_cast<std::chrono::microseconds>(stop - start);
cout << duration.count() << endl;

Chrono 라이브러리를 활용하여 seconds, milliseconds, microseconds, nanoseconds의 단위로 elapsed time을 구할 수 있다.
