Archimedes (287-212 B. C.) yog ib txwm inventor ntawm cov cuab yeej no, uas yog keeb kwm siv rau kev ywg dej hauv Nile delta thiab siv cov nkoj tawm. Kuv tau pom ib puas xyoo pua Archimedes ' ntsia hlau tseem ua hauj lwm twj tso dej hauv lub tshuab cua tshuab ntawm Schermerhoorn hauv xeev North Holland hauv Netherlands.
Kuj kom paub yog, cov khoom siv twg yog thawj Archimedes ntsia hlau siv txav?
Tej yam xws li nplej, xuab zeb, thiab sawdust ntws zoo ib yam li dej, thiab lwm yam Archimedes ntsia hlau tuaj yeem yog siv txav lawv thiab.
Tsis tas li ntawd, xyoo twg Archimedes ntsia hlau tsim? 287 B. C., ib.
Qhov thib ob, Archimedes ntsia hlau siv rau hnub no yog dab tsi?
Kev siv niaj hnub. Cov Archimedes Ntsia Hlau yog tseem siv hnub no hauv qee qhov kev txwv tsis pub siv (feem ntau yog siv hluav taws xob), thiab tuaj yeem muaj qhov loj me los ntawm ib lub quarter ntawm ib nti mus txog ze li ntawm 4 meters (12 feet) inch. Ib tug loj ntsia hlau los yog bank ntawm ntsia hlau tej zaum siv kom tso dej nag los nag los yog nqa dej los yog dej khib nyiab, piv txwv li.
Archimedes ntsia hlau zoo li cas?
Cov Archimedes ntsia hlau yog tsim los ntawm lub tog raj kheej hollow thiab a kauv part (ib kauv tuaj yeem nyob hauv, tab sis ntawm no koj yuav muab tso rau sab nraum lub tog raj kheej). Ib qho kawg yog muab tso rau hauv qhov chaw qis qis thiab lwm qhov kawg yog tilted mus rau hauv qhov chaw tawm ntau dua.

Vim li cas Archimedes ntsia hlau tseem ceeb?
Cov cuab yeej no tau siv ntau yam keeb kwm. Nws tau siv los tso dej tawm ntawm cov nkoj xau thiab dej nyab mines. Cov teb ntawm cov qoob loo tau watered los ntawm kev siv cov ntsia hlau rub dej los ntawm cov pas dej thiab cov dej ntws. Nws kuj tau siv los rov qab dej nyab, piv txwv li hauv Holland qhov twg ntau thaj av nyob hauv qab dej hiav txwv
Thaum twg yog computers thawj zaug siv suab paj nruag?
Lub ntiaj teb thawj lub computer ua si suab paj nruag yog CSIR Mark 1 (tom qab lub npe hu ua CSIRAC), uas tau tsim thiab tsim los ntawm Trevor Pearcey thiab Maston Beard los ntawm lig 1940s. Lej Geoff Hill programmed CSIR Mark 1 los ua suab paj nruag nrov los ntawm 1950s thaum ntxov

Dab tsi yog computer punch cards thawj zaug siv rau?
Punch cards (los yog 'punched cards'), tseem hu ua Hollerith phaib lossis IBM phaib, yog cov ntawv ntawv uas lub qhov yuav raug ntaus los ntawm tes ormachine los sawv cev cov ntaub ntawv hauv computer thiab cov lus qhia. Lawv yog ib tug dav-siv txhais tau tias ntawm inputing cov ntaub ntawv mus rau hauv lub computer thaum ntxov
Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
