Ntxig ib qho ntawm ib txoj haujlwm tshwj xeeb hauv cov npe txuas
- Hla mus Txuas daim ntawv teev npe mus rau txoj hauj lwm-1 nodes .
- Ib zaug txhua txoj haujlwm - 1 nodes yog traversed, faib lub cim xeeb thiab cov ntaub ntawv muab rau tus tshiab node .
- taw tes tus taw tes tom ntej ntawm qhov tshiab node mus rau tom ntej ntawm tam sim no node .
- taw tes tus pointer tom ntej ntawm tam sim no node mus rau qhov tshiab node .
Ntawm no, ua li cas koj ntxiv ib yam dab tsi rau ib daim ntawv txuas?
Cov txheej txheem ntawm LinkedList chav kawm:
- boolean add(Object item): Nws ntxiv cov khoom tom kawg ntawm daim ntawv.
- void add(int index, Object item): Nws ntxiv ib yam khoom ntawm qhov muab index ntawm daim ntawv.
- boolean addAll(Collection c): Nws ntxiv tag nrho cov ntsiab lus ntawm cov teev sau c rau hauv daim ntawv.
qhov twg yog qhov tshiab node ntxiv rau cov npe txuas? Cov nov node yog ib txwm ntxiv tom qab kawg node ntawm qhov muab Linked List . Piv txwv li yog tias muab Linked List yog 5-> 10-> 15-> 20-> 25 thiab peb ntxiv ib yam khoom 30 thaum kawg, ces tus Linked List ua 5->10->15->20->25->30.
Kuj Paub, Kuv yuav ua li cas ntxiv ib qho ntawm qhov kawg ntawm cov npe txuas?
Cov kauj ruam los ntxig rau ntawm qhov kawg ntawm Singly linked list
- Tsim cov node tshiab thiab xyuas kom meej tias qhov chaw nyob ib feem ntawm qhov tshiab node taw qhia rau NULL i.e. newNode->next=NULL.
- Hla mus rau qhov kawg ntawm cov npe sib txuas thiab txuas lub kawg ntawm cov npe nrog cov node tshiab, piv txwv li lub xeem node tam sim no taw tes rau qhov tshiab.
Koj txheeb cov npe txuas li cas?
Yuav ua li cas txheeb cov npe txuas nrog kev sib koom ua ke
- Yog tias: Daim ntawv teev npe muaj ib lossis tsawg dua, rov qab rau tib daim ntawv teev npe.
- Lwm yam: Faib cov npe rau hauv ib nrab siv cov kev faib ua haujlwm.
- Sort: Sort ?ob ob halves ntawm daim ntawv.
- Thaum kawg, ua ke cov npe txheeb.

Puas yog nws txaus ntshai rau ntsaws qhov txuas ntxiv rau hauv qhov txuas ntxiv?
Koj puas tuaj yeem txuas cov kab txuas txuas mus rau lwm qhov txuas txuas ntxiv? Ib zaug ntxiv, technically koj tuaj yeem ua tau, tab sis nws tsis pom zoo, raws li nws tau suav tias yog hluav taws kub. Thaum koj pib ntxiv cov hlua txuas ntxiv, koj khiav qhov kev pheej hmoo ntawm kev ua haujlwm ntev dhau thiab ua rau koj lub zog qis dua - tsis muaj kev nyab xeeb
Yuav ua li cas ua ob daim ntawv txuas DLL piv rau ib daim ntawv txuas SLL)?
Kev Taw Qhia rau Doubly linked List: Ib Daim Doubly Linked List (DLL) muaj qhov taw qhia ntxiv, feem ntau hu ua tus taw qhia yav dhau los, ua ke nrog tus taw tes tom ntej thiab cov ntaub ntawv uas muaj nyob rau hauv cov npe sib txuas ib leeg. SLL muaj cov nodes nrog tsuas yog cov ntaub ntawv teb thiab tom ntej txuas teb. Lub DLL tuav ntau lub cim xeeb dua li SLL vim nws muaj 3 daim teb
Dab tsi yog qhov txawv ntawm ob daim ntawv txuas thiab daim ntawv txuas txuas?
Ib daim ntawv txuas txuas txuas yog ib qho uas tsis muaj qhov pib lossis qhov kawg, tab sis lawv ua raws li cov qauv. Ib daim ntawv txuas ob npaug yog ib qho uas txhua qhov nodepoints tsis yog rau ntawm lub tom ntej node tab sis kuj mus rau yav dhau los
Kuv yuav ntxiv ib daim teb rau daim ntawv qhia SSRS li cas?
Hauv Daim Ntawv Qhia Cov Ntaub Ntawv pane, right-click lub dataset, thiab tom qab ntawd nyem Ntxiv Query Field. Yog tias koj tsis tuaj yeem pom Daim Ntawv Qhia Cov Ntaub Ntawv pane, los ntawm View menu, nyem Qhia Cov Ntaub Ntawv. Hauv nplooj ntawv teb ntawm Dataset Properties dialog box, nyem Ntxiv, thiab tom qab ntawd nyem Cov Lus Nug. Ib kab tshiab yog ntxiv rau hauv qab ntawm daim phiaj
Yuav ua li cas koj luam ib daim ntawv lo rau hauv daim ntawv dub?
