Submitted a C++ solution for a problem - 3ms.\n\nChanged the code a bit, submitted - 6ms.\n\nRestored the original code, submitted - 6ms\n\nI wonder if the perf measuring scenarios run the tests several times, taking averages, making sure deviation is small. If the tests run on virtual machines, how dedicated are those to our submissions?
