Raws li tau hais hauv JavaDoc, Arrays. xaiv siv dual-pivot Quicksort Quicksort Quicksort yog ib qho kev faib-thiab-tiav algorithm. Nws ua haujlwm los ntawm kev xaiv lub ntsiab lus 'piot' los ntawm array thiab muab faib rau lwm cov ntsiab lus rau hauv ob lub sub-arrays, raws li seb lawv tsawg dua lossis ntau dua li pivot. … Cov sub-arrays ces sorted recursively. https://en.wikipedia.org › wiki › Quicksort

on primitives. Nws muaj O(n log(n)) kev ua tau zoo thiab feem ntau nrawm dua li ib txwm siv (ib-pivot) Quicksort kev siv. Txawm li cas los xij, nws siv qhov ruaj khov, hloov kho, rov ua dua ntawm kev sib koom ua ke hauv kev tshawb fawb hauv computer, kev sib koom ua ke (kuj feem ntau sau raws li kev sib koom ua ke) yog ib qho txiaj ntsig, lub hom phiaj dav dav, thiab kev sib pivsorting algorithm. Feem ntau cov kev siv tsim ib qho kev ruaj khov, uas txhais tau hais tias qhov kev txiav txim ntawm cov khoom sib npaug yog tib yam hauv cov tswv yim thiab cov khoom tawm. https://en.wikipedia.org › wiki › Merge_sort

algorithm rau Array ntawm Cov Khoom.
Puas arrays txheeb nyob rau hauv ascending order?
Tib txoj hauv kev los txheeb cov array thawj zaug hauv qhov kev txiav txim nqis los yog, ua ntej txheeb cov array hauv kev nce qib thiab tom qab ntawd thim rov qab cov array hauv qhov chaw. Qhov no kuj muaj tseeb rau ob-dimensional primitive arrays. Hloov koj cov primitives rau lawv cov khoom sib xws.
Qhov twg yog qhov zoo tshaj rau array?
Quicksort . Quicksort yogib qho ntawm cov txiaj ntsig zoo tshaj plaws sorting algorithms, thiab qhov no ua rau nws yog ib qho ntawm feem ntau siv thiab. Thawj qhov uas yuav tsum tau ua yog xaiv tus lej pivot, tus lej no yuav cais cov ntaub ntawv, ntawm nws sab laug yog cov lej me dua nws thiab cov lej ntau dua ntawm sab xis.
Qhov kev txheeb xyuas algorithm twg yog qhov zoo tshaj plaws rau kev txheeb array?
Insertion sort khiav ntau npaum li cas yog tias cov array twb tau txheeb lossis "ze rau txheeb." Kev xaiv xaiv ib txwm ua O(n) swaps, thaum qhov kev sib txuas ua tiav O(n2) swaps hauv qhov nruab nrab thiab qhov phem tshaj plaws. Kev xaiv xaiv yog qhov zoo dua yog tias sau rau lub cim xeeb tseem kim dua li kev nyeem ntawv.
Puas yog arrays linear?
Yes, Arrays. sort (int) nyob rau hauv tag nrho Java txheem tsev qiv ntawv kev siv uas kuv paub, yog ib qho piv txwv ntawm kev sib piv raws li kev txheeb xyuas thiab yog li yuav tsum muaj qhov teeb meem phem tshaj plaws Ω(n log n). Tshwj xeeb, Oracle Java 7 siv dual-pivot quicksort variant rau cov lej ntau dhau, uas yeej muaj Ω(n2) qhov phem tshaj.
