@wyatt Now I'm intrigued. Does your university's data structures class cover implementing a hash table from scratch? Say one that maps either fixed-length or zero-terminated character strings to 32-bit integers. I ask because one thing that the ISO C standard library lacks is any sort of map, dictionary, or associative array data structure. It's not like a dynamic array, where a thin wrapper around realloc() is adequate. (hsearch() is non-ISO and allows only one hash table per process.)

#Undergraduate Disproves 40-Year-Old Conjecture, Invents New Kind of #HashTable
A young computer scientist and two colleagues show that searches within data structures called #hashtables can be much faster than previously deemed possible.

Sometimes a fresh perspective leads to revolutionary insights 💚. Without intending to Andrew Krapivin, as an undergraduate student 👨🎓, turned around the 40 years old paradidigm on #hashtable lookups 🗄️!
After the #DeepSeek results, another great example that #innovation does not always come from business cases or throwing billions 💰 and energy resources into the game. Sometimes it simply comes from curiosity and a different way of looking at a challenge!
