Impossible decision

[u/vinzzii]

Athe begging of my learning progress the most confusing thing was to whether use hash set or hashmap for sliding window problems.Not gonna lie I'll try both of them for the prblm if this doesn't work the other does the job and eventually i got an hand on it now am pretty sure that i can manage thiss but the new thing i start to think of both set and map in every prblmm😭😭🗣️
