A binary nrhiav yog ib simplistic algorithm npaj los nrhiav qhov chaw ntawm ib qho khoom khaws cia hauv ib daim ntawv teev npe. Muaj ob peb variations rau lub binary nrhiav hauv C qhov kev pab cuam, xws li kev sim rau kev sib npaug thiab tsawg-ntau tshaj ntawm txhua kauj ruam ntawm qhov algorithm.

Yog li ntawd, dab tsi yog binary nrhiav hauv C ++?

Nrhiav Binary hauv C++ Nrhiav Binary yog ib txoj hauv kev los nrhiav qhov yuav tsum tau muaj nyob rau hauv ib qho kev txheeb xyuas los ntawm kev rov ua dua ib nrab ntawm cov array thiab nrhiav hauv ib nrab. Txoj kev no yog ua los ntawm kev pib nrog tag nrho cov array. Ces nws yog halved. Ib qho kev pab cuam uas qhia tau hais tias binary nrhiav hauv C ++ yog muab hauv qab no.

binary search nrog piv txwv yog dab tsi? Binary nrhiav saib rau ib yam khoom tshwj xeeb los ntawm kev sib piv cov khoom nruab nrab feem ntau ntawm cov khoom sau. Yog tias qhov kev sib tw tshwm sim, ces qhov ntsuas ntawm cov khoom raug xa rov qab. Yog tias qhov khoom nruab nrab loj dua qhov khoom, ces cov khoom raug tshawb nrhiav hauv sub-array rau sab laug ntawm cov khoom nruab nrab.

Qhov thib ob, dab tsi yog txhais los ntawm kev tshawb nrhiav binary?

Hauv computer science, binary nrhiav , kuj hu ua ib nrab-interval nrhiav , logarithmic nrhiav , los yog binary chob, a nrhiav algorithm uas pom txoj hauj lwm ntawm lub hom phiaj tus nqi nyob rau hauv ib tug sorted array. Binary nrhiav piv cov hom phiaj tus nqi rau qhov nruab nrab ntawm cov array.

Kev tshawb nrhiav binary siv rau dab tsi?

Hauv nws daim ntawv yooj yim tshaj plaws, binary nrhiav yog siv rau sai sai nrhiav ib tug nqi nyob rau hauv ib tug sorted sequence (xav txog ib tug sequence ib tug dog dig array rau tam sim no). Peb mam li hu tus nqi nrhiav lub hom phiaj tus nqi kom pom tseeb. Binary nrhiav tuav ib qho kev sib txuas ua ke ntawm qhov pib ib ntus qhov twg lub hom phiaj tus nqi muaj tseeb nyob.
