Heap Sib
Ib yam li ntawd, qhov kev txheeb xyuas algorithm twg muaj lub sijhawm zoo tshaj plaws?
Rau qhov zoo tshaj plaws Insertion Cai thiab Heap Sib yog qhov zoo tshaj plaws raws li lawv cov ntaub ntawv zoo tshaj plaws khiav lub sij hawm nyuaj yog O (n). Rau qhov nruab nrab qhov zoo tshaj plaws asymptotic khiav lub sij hawm nyuaj yog O (nlogn) uas yog muab los ntawm Merge Sort, Heap Sib , Ceev Sort. Rau qhov phem tshaj plaws khiav lub sij hawm complexity yog O (nlogn) uas yog muab los ntawm Merge Sort, Heap Sib.
Tsis tas li ntawd, dab tsi yog asymptotic runtime complexity? asymptotic sij hawm nyuaj . (Definition) Txhais: Qhov txwv tus cwj pwm ntawm lub sij hawm ua tiav ntawm ib qho algorithm thaum qhov loj ntawm qhov teeb meem mus rau infinity. Qhov no feem ntau yog qhia nyob rau hauv loj-O cim. Saib thiab asymptotic qhov chaw nyuaj.
Dhau li ntawm no, qhov algorithm twg yog qhov zoo tshaj rau kev txheeb xyuas?
Quicksort
Dab tsi yog qhov nyuaj ntawm sorting algorithm?
Sijhawm Complexities ntawm tag nrho Sorting algorithms
| Algorithm | Lub sij hawm nyuaj | |
|---|---|---|
| Zoo tshaj | phem tshaj | |
| Npuas Sort | Ω(n) | O(n^2) |
| Insertion Sort | Ω (n) | O(n^2) |
| Heap Sib | Ω(n log(n)) | O(n log(n)) |

Dab tsi yog qhov zoo tshaj plaws algorithm rau kev soj ntsuam kev xav?
Kev soj ntsuam kev xav yog cov cuab yeej zoo sib xws uas siv los txheeb xyuas cov kev xav ntawm cov neeg siv khoom thiab muaj ntau lub algorithms tuaj yeem siv los tsim cov ntawv thov rau kev soj ntsuam kev xav. Raws li tus tsim tawm thiab ML cov kws tshaj lij SVM, Naive Bayes thiab qhov siab tshaj plaws entropy yog qhov zoo tshaj plaws saib xyuas tshuab kev kawm algorithms
Dab tsi yog qhov zoo tshaj plaws tsib qhov tsis zoo ntawm koj lub operating system?
Qhov feem ntau cov software kev ruaj ntseg vulnerabilities muaj xws li: ploj ntaub ntawv encryption. OS command txhaj. SQL txhaj. Tsis pub dhau. Tsis muaj kev lees paub rau kev ua haujlwm tseem ceeb. Kev tso cai ploj lawm. Unrestricted upload cov ntaub ntawv txaus ntshai hom. Kev cia siab rau cov khoom siv tsis ntseeg siab hauv kev txiav txim siab kev ruaj ntseg
