Cov yam ntxwv tseem ceeb ntawm Kev Sib Koom Tes: Kev Sib Koom Sib Koom yog siv tau rau kev txheeb cov npe txuasKev sib koom ua ke yog qhov ruaj khov uas txhais tau tias tib lub ntsiab lus hauv ib qho array tuav lawv txoj haujlwm qub nrog kev hwm rau ib leeg. … Qhov chaw complexity ntawm Merge txheeb yog O(n).
Lub hom phiaj ntawm kev sib koom ua ke yog dab tsi?
Mergesort hauv Objective-C ?
Lub mergesort algorithm yog ib qho kev txheeb xyuas algorithm tsim los ntawm John von Neumann rov qab rau xyoo 1945. Lub tswv yim dav dav yog txhawm rau sau cov ntaub ntawv thiab rov muab faib nws mus rau hauv cov npe me kom txog rau thaum nws yooj yim heev los txheeb cov ntsiab lus hauv txhua daim ntawvCes, muab txhua daim ntawv thiab muab lawv rov qab ib daim ntawv teev npe.
Yuav ua li cas sib koom ua ke txhim kho kev ua tau zoo?
Siv ntxig txheeb rau cov subarrays me Peb tuaj yeem txhim kho feem ntau cov txheej txheem rov ua dua los ntawm kev tuav cov xwm txheej me me sib txawv. Hloov mus rau kev sib cais rau cov subarrays me me yuav txhim kho lub sijhawm ua haujlwm ntawm kev sib koom ua ke los ntawm 10 mus rau 15 feem pua. Kuaj seb puas yog array twb nyob rau hauv kev txiav txim.
Vim li cas kev sib koom ua ke zoo dua li kev ua npuas?
(1) Merge-sort xav tau ib qho chaw pabcuam (qhov chaw ntxiv) txhawm rau txheeb thiab ua rau lub cim xeeb nkag tau ntau dua (2) Yog tias cov ntaub ntawv twb tau txheeb xyuas lawm, Bubble-sort yuav tsis txav ib qho twg. … Txawm li cas los xij, Merge-sort yog O(n log n) thiab Bubble Sort yog O(nn), yog li ntawd rau txhua yam tsim nyog cov ntaub ntawv Merge-xws yuav outperform Bubble sort.
Yuav ua li cas rau kev sib koom ua ke?
Ib qho piv txwv ntawm kev sib koom ua ke. Ua ntej faib cov npe rau hauv chav tsev tsawg tshaj plaws (1 lub ntsiab), tom qab ntawd sib piv txhua lub caij nrog cov npe nyob ib sab los txheeb thiab sib koom ua ke ob daim ntawv teev npe nyob ib sab Feem ntau cov kev siv tsim ib qho ruaj khov, uas txhais tau hais tias qhov kev txiav txim ntawm cov khoom sib npaug yog tib yam hauv cov khoom siv thiab cov khoom siv.…
