Heapsort yog kev sib piv-raws li kev txheeb xyuas algorithm uas siv cov ntaub ntawv binary heap. Zoo li mergesort mergesort Hauv computer science, 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 piv-raws li sorting 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
Kev sib koom ua ke - Wikipedia
heapsort muaj lub sijhawm ua haujlwm ntawm O (n log n), O (n\log n), O (nlogn), thiab zoo li kev sib cais, heapsort xaiv hauv qhov chaw, yog li tsis xav tau qhov chaw ntxiv thaum lub sijhawm xaiv.
Qhov chaw nco qhov xav tau ntawm heap yog dab tsi?
Heap sort runs in O (n lg (n)) O(n\lg(n)) O(nlg(n)) lub sij hawm, uas scales zoo li n loj hlob. Tsis zoo li quicksort, tsis muaj qhov phem tshaj plaws O (n 2) O (n ^ 2) O (n2) complexity. Qhov chaw zoo. Heap sort take O (1) O(1) O(1) space.
Vim li cas heap so O 1 qhov chaw nyuaj?
2 Teb. HEAP SORT siv MAX_HEAPIFY muaj nuj nqi uas hu nws tus kheej tab sis nws tuaj yeem ua tau siv qhov yooj yim thaum lub voj voog thiab yog li ua rau nws ua haujlwm rov qab uas tsis siv qhov chaw thiab vim li no Chaw Complexity ntawm HEAP SORT tuaj yeem txo musO(1).
Dab tsi yog qhov tseeb ntawm heap?
Heap sort is a kev sib piv-raws li kev txheeb xyuas raws li Binary Heap cov ntaub ntawv qauv. Nws zoo ib yam li kev xaiv xaiv qhov twg peb xub pom qhov tsawg kawg nkaus thiab tso qhov tsawg kawg nkaus ntawm qhov pib. Peb rov ua tib yam txheej txheem rau cov khoom seem.
Yuav ua li cas yog txoj hauj lwm ntawm 5 thaum lub max heap?
5 yuav yog at root.

Leej twg tau xaiv rau lub tsev kawm ntawv xaiv tsa?
Leej twg xaiv cov xaiv? Kev xaiv txhua lub Xeev cov neeg xaiv tsa yog ib qho txheej txheem ob feem. Ua ntej, cov nom tswv hauv txhua lub Xeev xaiv cov neeg xaiv tsa uas muaj peev xwm ua ntej kev xaiv tsa. Qhov thib ob, thaum lub sijhawm xaiv tsa dav dav, cov neeg pov npav hauv txhua lub Xeev xaiv lawv lub Xeev cov neeg xaiv tsa los ntawm kev pov npav lawv.
Puas yog cov neeg taug kev ntxiv tau txais qhov lawv xav tau?
Lawv xav tau dab tsi? Tom qab Tsov Rog Ntiaj Teb Zaum 1, Teb Chaws Asmeskas Congress tau pov npav los muab cov tub rog qub tub rog uas tawm tsam hauv tsov rog tau nyiaj ntxiv Lawv yuav tau them $ 1.25 rau txhua hnub lawv ua haujlwm txawv teb chaws thiab $ 1.
Puas yog cov nqi them tas li xav tau lossis tsis tau xav txog?
Cov nuj nqis tas li yog ib yam thiab cov nqi uas xav tau koj them txhua lub hlis, xws li qiv tsev lossis nqi xauj tsev, daim nqi xov tooj thiab them nyiaj qiv nyiaj rau tub ntxhais kawm . Puas yog cov nqi ruaj khov? Rau tus kheej lub hom phiaj kev siv nyiaj txiag, cov nuj nqis tas li yog cov nqi uas koj tuaj yeem kwv yees nrog kev ntseeg siab vim tias lawv tsis hloov ntawm hli mus rau hli lossis lub sijhawm mus rau lub sijhawm .
Kuv puas xav tau cov ntaub ntawv ntxiv ntxiv?
Thaum cov ntaub ntawv ntxiv ntxiv muab ntau dua hloov pauvthiab granularity (lub sijhawm ntawm kev thaub qab), lawv muaj lub koob npe nrov rau kev siv sijhawm ntev dua vim tias qhov thaub qab yuav tsum tau rov ua dua los ntawm qhov kawg tag nrho thaub qab thiab tag nrho cov incremental backups txij li thaum .
Puas yog qhov kev xav txuas ntxiv tau daws tau?
Tab sis tom qab ntawd Andrew Wiles tau daws tau nws hauv 1994. Qhov kev xav tsis tu ncua yog ib qho teeb meem ntawm ntau yam sib txawv; peb yeej muaj peev xwm ua pov thawj tias nws tsis tuaj yeem daws nws siv txoj hauv kev tam sim no, uas tsis yog qhov tshwm sim tsis paub tseeb hauv lej .
