Xazulula amaphazili e-Kakuro

Kulo mhlahlandlela sinikeza amathiphu ahlukahlukene awusizo okuxazulula amaphazili e-Kakuro, anobunzima obusukela kwabaqalayo kuya ezingeni lochwepheshe.

Ukufingqa imithetho: I-Kakuro ngumdlalo wephazili ebhodini elifana namagama aphambene lapho kusetshenziswa khona izinombolo ukuze zifinyezwe zibe amanani achazwe ezikweleni 'zencazelo' zebhodi. Ngaphezu kwalokho, ngaphakathi kweqembu ngalinye lesamba, inombolo ngayinye ingavela kanye kuphela.

Indlela yendabuko yokuxazulula iphazili yeKakuro iwukuqhubeka kancane kancane: ngokusebenzisa ulwazi olukhona ebhodini, ungathola ngokuqinisekile inani leseli elithile elingathatha inani elilodwa kuphela elingenzeka. Bese lelo nani liyagcwaliswa bese inqubo iphindwa kuze kube yilapho wonke amaseli ebhodi esetholakele.

Kwezinye izimo, ayikho ibhodi elithile elinokuthile okungenzeka kube kanye kuphela. Kulezo zimo, ngalinye lala mathuba kudingeka lihlolwe lodwa futhi lisuswe ngokuphikisana kuze kube yilapho kusele isinyathelo esisodwa kuphela.

Sethula ngezansi izindlela eziningana zokuthuthuka ekuxazululeni iphazili yangempela.

Izibalo ezihlukile zezincazelo ezithile

Kunezincazelo ezithile ezingaxazululwa ngendlela ethile kuphela:

• isamba esingu-3 (esidlula amaseli amabili) sizohlala singu-1 + 2.
• isamba esingu-4 (esidlula amaseli amabili) sizohlala singu-1 + 3.
• isamba esingu-17 (esidlula amaseli amabili) sizohlala singu-8 + 9.
• isamba esingu-6 (esidlula amaseli amathathu) sizohlala singu-1 + 2 + 3.
• isamba esingu-24 (esiphezulu kwamaseli amathathu) sizohlala singu-7 + 8 + 9.

njalo njalo... Ngokuvamile ungazulazula kugridi yeKakuro phezu kwenombolo yencazelo bese kuvela ithuluzi eliqukethe wonke amathuba okubhala leso sibalo ngamadijithi ahlukile enanini lamaseli atholakalayo.

Izibalo ezingabhalwa ngendlela ehlukile ngokuvamile ziyizibalo eziphansi noma izibalo eziphezulu eziphoqa izinombolo eziphansi/eziphezulu empendulweni ukuze zifinyelelwe.

Ukuba nendlela ehlukile yokubhala isamba kuyasiza, kodwa khumbula ukuthi zonke izinguquko ziyasebenza futhi kusadingeka uthole ukuthi iyiphi inguqulo yangempela okufanele uyisebenzise ebhodini.

Imikhawulo yomugqa/ikholomu

Kumaseli aphuzi aqokonyiswe ngenhla, kunendlela eyodwa kuphela yokubhala isamba: 4 = 1 + 3. Kodwa-ke kusadingeka sithole ukuthi iyiphi i-permutation (1 + 3 noma 3 + 1) okufanele siyisebenzise.

Kuvela ukuthi incazelo eqondile engu-26 iyasisiza: isamba phakathi kwamaseli angu-4 angaqukatha idijithi 1 singaba okungenani u-1 + 9 + 8 + 7 = 25. Njengoba isamba sethu singama-26, kuvela ukuthi idijithi 1 ayikwazi ukuba yingxenye yesamba. Ngakho-ke, okuwukuphela kwe-oda elisele lezikwele eziphuzi ngu-3 + 1.

Izincazelo izindawo zokuhlangana

Ebhodini elingenhla, izikwele eziphuzi ezivundlile zingabhalwa njengo-6 = 1 + 5 noma u-6 = 2 + 4. Isamba esiphuzi esivundlile singabhalwa kuphela njengo-29 = 5 + 7 + 8 + 9.

Isikwele esiphuzi esitholakala ekuxhumaneni kwalezo zincazelo ezimbili zesamba kumele sibe nenombolo efanayo, ngakho-ke kumele kube nenombolo efanayo ekhona ezincazelweni ezivundlile neziqondile ukuze kwabelwane ngazo. Ngokubheka amathuba angenhla singathola kalula ukuthi u-5 uwukuphela kwenombolo ehlonipha le nqubo.

Le ndlela isebenza kahle kakhulu lapho kuhlanganiswa isamba esincane nencazelo yesamba esiphezulu. Izincazelo zesamba esincane kanye nesamba esiphezulu yilezo ezinenombolo yencazelo yesamba esiphansi noma esiphezulu (6 kanye no-29 ngokulandelana kwesibonelo sethu) uma kuqhathaniswa nenani lamaseli atholakalayo. Ngenxa yokuthi u-6 uphansi kakhulu, uzophoqa izinombolo eziphansi ekumelweni kwesamba, kanti u-29 uzophoqa izinombolo eziphezulu (ukuze kufinyelelwe lezi zibalo kusetshenziswa inombolo enikeziwe yamaseli). Ngakho-ke ukuhlangana kwezinombolo eziphansi neziphezulu cishe kuzoqukatha umuntu oyedwa kuphela wenani langempela leseli.

Amanani amancane / aphezulu eqembu lesamba

Ngezinye izikhathi kuyasiza ukuthola inani eliphakeme noma eliphansi leqembu lesamba. Lokhu kungakunikeza umqondo wokuthi lingakanani ibanga elivumelekile lezinombolo zalelo nani elithile, okuzokusiza ukuthi wenze ukuxhumana neminye imikhawulo futhi uthole izabelo ezihlukile ebhodini.

Esibonelweni esingenhla, amaseli aphuzi aqondile amukela kuphela amanani alingana no-7 noma ngaphezulu. Uma uzama ukwabela u-6, ungathola kalula ukuthi u-6 + 9 + 8 = 23 ngakho-ke isamba sencazelo esingu-24 ngeke sitholakale.

Ngenxa yokuthi u-7 ungowenani eliphansi, incazelo evundlile eno-8 njengesamba iphoqa u-7 kuleso simo.

Isiphetho

Ukuzijwayeza kuyindlela engcono kakhulu yokubona ukuthi lesi seluleko singasetshenziswa kanjani emidlalweni yangempela yeKakuro. Dlala iphazili ngempela. Sikufisela inhlanhla nokuzijabulisa okuningi!
