Given profiler samples from running code, find the slowest part in the code.

Focus on your approach to analyzing profiler samples, emphasizing how you would identify performance bottlenecks in the code. Discuss the specific metrics you would look for, such as CPU time, memory usage, or call frequency, and how these metrics can guide your investigation. Be prepared to explain how you would prioritize which parts of the code to optimize first based on the profiler data. Additionally, consider how you would validate your findings and measure the impact of any optimizations you propose.
