感觉部署私有云的电费 都 赶得上 厂商的服务费了

accuracy 的值越大，精确度越高

public static long sum(Integer ... numbers) throws InterruptedException {
long accuracy = 1000L;
long startTime = System.currentTimeMillis();
for (Integer number : numbers) {
Thread.sleep(number * accuracy);
}
return (System.currentTimeMillis() - startTime) / accuracy;
}
