> 2\. `System.currentTimeMillis()` for CPU time and calculate memory usage
by subtracting free memory from total memory using `Runtime.getRuntime()`.
Insert these measurements at critical points in the algorithm's execution path
and log the results for analysis.
>
> Example code snippet for manual instrumentation:
>
> ```java
> long startTime = System.currentTimeMillis();
> long startMemory = Runtime.getRuntime().totalMemory() -
Runtime.getRuntime().freeMemory();
>
> // Algorithm execution code
>
> long endTime = System.currentTimeMillis();
> long endMemory = Runtime.getRuntime().totalMemory() -
Runtime.getRuntime().freeMemory();
>
> LOG.debug("Execution time: " + (endTime - startTime) + "ms");
> LOG.debug("Memory used: " + (endMemory - startMemory) + " bytes");
> ```

analysis, integrate JMH to benchmark th
修改代码，编译运行之后，输出的log文件应该在哪个目录下
