Incazelo ebonakalayo ye-algorithm ye-MurmurHash3C hash, ekhombisa idatha yokufaka, ama-loop okucubungula, izigaba zokuqedela, kanye nomphumela we-hash kumdwebo ocacile osuka kwesobunxele uye kwesokudla.
MurmurHash3C Algorithm Overview
Izinguqulo ezitholakalayo zalesi sithombe
Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.

Incazelo yesithombe
Isithombe siwumfanekiso obanzi, ogxile endaweni ethile ochaza ngokubonakalayo ukugeleza kwezinga eliphezulu kwe-algorithm ye-MurmurHash3C hashing ngendlela elula nengakhethi ubuchwepheshe. Ingemuva liyi-gradient eluhlaza okwesibhakabhaka ebushelelezi, enikeza umdwebo umuzwa wesimanje, wezobuchwepheshe ngenkathi igcina umehluko omkhulu nezici zangaphambili. Ephakathi nendawo, isihloko esikhulu sifunda ukuthi “MurmurHash3C Algorithm,” negama elithi “Hash” ligqanyiswe ngethoni eluhlaza okwesibhakabhaka ekhanyayo ukugcizelela umqondo we-hashing. Umugqa ongaphansi ogobile uhlukanisa isihloko nomdwebo oyinhloko.
Ngakwesobunxele kude kunebhulokhi eliyindilinga elinsomi elibhalwe ukuthi “I-INPUT DATA.” Ngaphakathi kwalo kunemigqa eqoshiwe yezinombolo ezimbili ezifana no-01011001, 10110101, kanye no-11010011, elandelwa yi-ellipsis ukukhombisa ukuthi idatha iyaqhubeka. Ngezansi kwaleli bhulokhi kunesihloko esincane esithi “CHUNKED & MIXED,” esikisela ukuthi okokufaka okungavuthiwe kuqala kuhlukaniswe kube yizicucu futhi kulungiselelwe ukucutshungulwa. Umcibisholo omhlophe ojiyile ukhomba kusukela kuleli bhulokhi lokufaka uye enkabeni yomdwebo.
Ingxenye ephakathi ifulekwe uhlaka oluyindilinga oluneziqeshana olunesihloko esithi “PROCESSING LOOPS,” kanye nesihloko esincane ngaphansi kwalo esithi “REPEATED ROUNDS.” Ngaphakathi kwale ndawo kunezithonjana ezintathu ezinemibala ezihlelwe ngokuvundlile. Ithoni yokuqala iluhlaza okwesibhakabhaka futhi iqukethe amathuluzi okunqamula angabonakali, amele ukuxuba okujwayelekile noma ukusebenza okufana nokuphindaphinda. Ithoni yesibili iluhlaza okwesibhakabhaka futhi ibonisa umcibisholo oyindilinga, ofanekisela ukujikeleza noma ukuhlela kabusha. Ithoni yesithathu inombala onsomi futhi ibhalwe ngokucacile ukuthi “XOR,” okubonisa isinyathelo esikhethekile noma esicacile. Imicibisholo emhlophe ixhuma lezi zithonjana ezintathu ngokulandelana, okubonisa ukuthi idatha igeleza kuzo ngokuphindaphindiwe njengengxenye ye-core loop ye-algorithm.
Ukusuka endaweni yokucubungula, umcibisholo omkhulu uholela ohlangothini lwesokudla lwesithombe, lapho kuvela khona ingxenye ehlanganisiwe enesihloko esithi “FINALIZATION”. Lesi sigaba siqukethe amabhlogo amathathu angunxande ahlanganisiwe asukela kowolintshi kuya kobomvu. Ibhloko eliphezulu libhalwe ukuthi “Final Mix” futhi liboniswe ngezithonjana ezincane zegiya ukuze kuphakanyiswe isigaba sokugcina sokuxuba. Ibhloko eliphakathi libhalwe ukuthi “Bit Shift” ngophawu lomcibisholo okhomba ngakwesokudla, okusho ukulungiswa kwezinga lebhithi. Ibhloko elingezansi libhalwe ukuthi “Modulo” futhi lifaka uphawu lwephesenti, olumelela isinyathelo sokugcina sokunciphisa noma sokulungisa. Lawa mabhlogo amathathu aqondaniswe ngokuqondile futhi axhunywe ukugeleza okuphelele kusuka kwesobunxele kuya kwesokudla.
Ngakwesokudla kakhulu kukhona ibhlogo eliyindilinga eliluhlaza okwesibhakabhaka elibhalwe ukuthi “HASH OUTPUT.” Ngaphansi kwelebula kukhona umucu omfushane wesitayela se-hexadecimal, “8F3A12C7,” osebenza njengesibonelo senani lokugcina le-hash. Umcibisholo omhlophe uxhumanisa isigaba sokuqedela kule bhloko yokuphuma, uqedela ipayipi elibonakalayo.
Sekukonke, isithombe sigwema ama-constant obuchwepheshe asezingeni eliphansi futhi esikhundleni salokho sigxila ezimpawini ezinembile, izigaba ezinemibala, kanye nemicibisholo eqondisa indlela. Ukwakheka kubonisa ngokucacile ukuthi i-MurmurHash3C iguqula idatha yokufaka enama-binary ngokusebenzisa imisebenzi yokuxuba ephindaphindwayo, elandelwa isigaba sokuqedela, ukuze ikhiqize umphumela we-hash ohlangene.
