This optimization was flagged by a tool I’m developing, which performs code inspection to identify potential performance improvements. However, it doesn’t measure execution times, so I haven’t benchmarked the actual impact yet. From a theoretical perspective, the change makes sense since the previous implementation performed lookups in a list (O(n)) while the new approach uses a set (O(1)). Would you be able to help me create a proper benchmark for this case? |
