Ib ntu twg ntawm cov ntaub ntawv ntawm tib hom tuaj yeem raug sawv cev los ua ib daim npe. Cov npe yuav raug txiav txim thiab tsis tuaj yeem. Nyob rau hauv rooj plaub tom kawg, ua haujlwm nrog cov ntaub ntawv, nrhiav tus nqi xav tau, thiab nkag mus rau cov ntsiab lus sau tau ua rau muaj kev nyuaj. Cov npe ntawm txoj hlua hloov tau feem ntau yog txheeb raws cov niam ntawv. Muaj ntau ntau txoj kev xaiv, hauv txhua kis koj yuav tsum xaiv qhov kev pom zoo tshaj plaws.
Cov Lus Qhia

Thaum xaiv txoj kev xaiv qhov zoo tshaj plaws, muaj ob yam uas yuav tau xav txog: lub sijhawm siv rau kev ua haujlwm sorting thiab qhov ntau npaum li cas ntawm kev nco yuav tsum muaj rau kev pab cia. Txheeb cov algorithms uas tsis tas yuav muaj qhov cim xeeb ntxiv yog hu ua "hauv qhov chaw" xaiv. Ib qho ntawm qhov yooj yim rau kev ua yog qeeb qeeb ua npuas, uas scans txhua khub ntawm cov khoom hauv daim ntawv teev npe thiab pauv qhov chaw nyob ntawm qhov kev txiav txim siab xav tau.

Muaj ib txoj kev xaiv tau sai dua los ntawm kev pom yam tsawg kawg lossis ntau tshaj hauv cov npe. Txheeb cais cov ntawv sau sib txawv, txhua zaus koj nkag mus hauv daim ntawv, koj yuav tsum nrhiav nws lub siab tshaj plaws - qhov no yuav yog txoj hlua pib nrog tus tsiaj ntawv nyob ze rau thaum pib ntawm tus niam ntawv. Thaum pom, txoj hlua yog swapped nrog cov khoom thib ib hauv cov npe ntawm daim ntawv hla dhau. Raws li kev txiav txim siab ntxiv ntawm daim ntawv, thawj qhov chaw yog cais tawm, tom ntej no lub siab tshaj plaws tau nrhiav, muab tso rau hauv qhov chaw thib ob, thiab lwm yam. Cov cai ntawm qhov kev pab cuam sorting hauv C ++ los ntawm tus txheej txheem ntawm kev nrhiav cov khoom siab tshaj plaws ntawm daim ntawv: hlua Arr [20], cTemp; rau cov menyuam N = 20, Max, Pos; rau (int kuv = 0; kuv <N- 1; i ++) {Max = Arr ; Pos = i; rau (rau cov j = 0; j <N; j ++) {yog (Arr [j] <Max) {Max = Arr [j]; Pos = j; } cTemp = Arr ; Arr = Arr [Pos]; Arr [Pos] = cTemp;.}}

Txoj kev xaiv zoo tshaj plaws rau kev txiav txim cov hlua cov ntaub ntawv hauv ib daim ntawv teev yog ntxig cov teeb meem. Nws lub ntsiab lus dag hauv qhov tseeb tias nrog txhua qhov dhau los ntawm daim ntawv teev npe, muaj ib qhov xaj ntawm cov npe ntawm qee cov ntsiab lus, yog li, cov khoom txuas ntxiv tom qab txiav txim siab muab tso rau hauv qhov chaw tsim nyog hauv cov npe. C ++ code ntawm kev nkag mus tshawb cov teeb meem sib txawv: hlua Arr [20], cTemp; int N = 20; rau (rau cov menyuam kuv = 1, j = 0; kuv <N; i ++) {cTemp = Arr ; j = i - 1; thaum (cTemp <Arr [j]) {Arr [j + 1] = Arr [j]; j--; yog (j <0) tawg; Arr [j + 1] = cTemp;.}}
