Indlela yokuxazulula amaphazili e-Futoshiki ngempumelelo

Esifundweni esilandelayo, amasu ayisisekelo nathuthukile okuxazulula amaphazili e-Futoshiki anikezwa isinyathelo ngesinyathelo, kanye nemifanekiso ehambisana nawo ukuze kuboniswe izindlela ezilungiselelweni ezithile zebhodi.

Isiqalo sokufinyelela isisombululo yincazelo yomdlalo ngokwawo: I-Futoshiki idinga umsebenzisi ukuthi athole ibhodi lapho inombolo ngayinye ivela khona kanye kumugqa ngamunye nekholomu, ngokuhlonipha ukungalingani kwebhodi. Ngokusebenzisa le ndlela, intuthuko eya esixazululweni ingenziwa ngokugcwalisa, isinyathelo ngesinyathelo, izikwele zebhodi ezingenalutho ezinezinombolo ezithile ngoba yizo kuphela eziyindlela yokuhlonipha imikhawulo yebhodi.

Ukukhishwa kwekholomu kanye nomugqa

Uma ikholomu nomugqa wesikwele sekuvele kuqukethe zonke izinombolo ezingaba khona, ngaphandle kweyodwa, khona-ke leso sikwele kumele sibe nenombolo engekho. Esibonelweni esingenhla, isikwele esiluhlaza kumele sibe ngu-4 ngoba ngeke sivunyelwe ukuba nanoma yiliphi elinye inani njengoba ezinye izinombolo ezingaba khona sezivele zitholakale emgqeni waso noma kukholomu yaso.

Uchungechunge lokungalingani

Uma ubona uchungechunge lokungalingani, kungaba < (konke kukhuphuka) noma > (konke kuhla), olulingana ngosayizi nosayizi webhodi, khona-ke lolo chungechunge kumele lube uchungechunge olusukela ku-1 kuya kubude bebhodi. Ubude bochungechunge buqinisekisa ukuthi lolu chungechunge luwukuphela kwesisombululo esingaba khona esanelisa isimo se-monotone esibekwa uchungechunge lokungalingani.

Amanani aphansi naphezulu aphoqelelwe

Izikwele ezingaphansi kuka 2 kumele zibe nenani elingu-1 ngokungaqondile njengoba kuyilona kuphela inani elivumelekile ebhodini elihlonipha leso simo. Ngokufanayo, izikwele ezinkulu kunosayizi webhodi ngaphandle kuka-1 kumele zilingane nosayizi webhodi. Esibonelweni esingenhla, inani elikhona kuphela lesikwele esiluhlaza (ngaphansi kuka 2) lingu 1 .

Ukukhishwa kwamanani amancane naphezulu

Izikwele ezinkulu kunezinye izikwele azikwazi ukuba yi-1 , inani eliphansi kakhulu elivunyelwe ebhodini, njengoba lingekho inani elincane kune 1 . Ngokufanayo, izikwele eziphansi kunezinye izikwele azikwazi ukuqukatha inani eliphezulu elivunyelwe, njengoba bekungekho lutho olukhulu olungagcwaliswa ngakolunye uhlangothi lokungalingani. Esibonelweni esingenhla, i-1 ayikwazi ukugcwaliswa ezikweleni ezibomvu njengoba zonke zinkulu kunezinye izikwele zebhodi, ngakho-ke okuwukuphela kokubekwa okungenzeka kwe -1 emgqeni wokuqala webhodi yisikwele esiluhlaza.

Ukuhlanganisa imithetho

Ngezinye izikhathi imithetho eminingi kumele isetshenziswe ukuze kufinyelelwe esiphethweni. Lokhu kunjalo esibonelweni esingenhla, lapho sizama ukubeka inani elingu 1 emgqeni wesibili webhodi. Isikwele sokuqala esibomvu siyasuswa ngenxa yokukhishwa kwekholomu (sesivele sino- 1 kuleyo kholomu), kuyilapho izikwele zesibili nezesithathu ezibomvu zisuswa ngenxa yokukhishwa kwamanani amancane njengoba lezo zindawo zinokungalingani 'okukhulu kuno' okuhlobene nazo. Ngakho-ke isikwele esiluhlaza sihlala siyindawo kuphela engenzeka yokubeka u-1 kulowo mugqa.

Amathuba okuphindaphinda

Ngezinye izikhathi, ikakhulukazi emabhodini anzima, azikho ezinye izindlela zokuthola inombolo efanele yesikwele ngaphandle kokucwila emiphumeleni yalokho okungenzeka kuze kube yilapho kufinyelelwa ekuphikisaneni. Esibonelweni esingenhla, zonke izikwele ezibomvu neziphuzi ekuqaleni azinalutho. Sifuna ukuthola ukuthi isikwele u-A siqukethe u-1 noma u-2 . Sicabanga ukuthi siqukethe u-2 bese sihlola ukuze sibone ukuthi sifinyelela yini ekuphikisaneni okusekelwe kulokhu kucabanga.

Uma isikwele A sino- 2, khona-ke isikwele B sizoba no- 1 (inani elisele kuphela emgqeni ongezansi). Isikwele C singaba ngu-1 noma u-2 njengoba sinochungechunge lokungalingani oludinga ukuba nezinombolo ezimbili ezinkulu ezitholakalayo, kodwa manje asikwazi ukuba ngu-1 ngenxa yokukhishwa kwekholomu yesikwele B, ngakho isikwele C singu- 2 , kanti isikwele D singu- 3 (inani kuphela eliphakathi kuka-2 no-4). Ngenxa yokukhishwa kwekholomu, isikwele E singu 1 kanti isikwele F singu 3 .

Manje, uma sibheka izikwele eziwolintshi, sibona ukuphikisana: uma isikwele u-G besizoba ngu 2, isikwele u-H besizoba ngu 3 noma u-4 , okungavunyelwe ngenxa yokukhishwa komugqa. Uma isikwele u-G besizoba ngu 3, isikwele u-H besizoba ngu 4 okungavunyelwe ngenxa yesizathu esifanayo. Njengoba singasenawo amanani asele esikwele u-G, kusho ukuthi sifinyelele ekunqandeni futhi ukucabanga kwethu kokuqala bekungalungile: u-2 akuyona isinyathelo esivumelekile sesikwele u-A, ngakho-ke singaqhubeka futhi sibeke u-1 kuso, okuwukuphela kwenani elingenzeka.

Iziphetho

Sibonise ngenhla ukuthi ungayixazulula kanjani ngempumelelo iphazili ye-Futoshiki ngokumboza uhla lwamasu angakusiza ukuthi uthole isinyathelo esilandelayo ngisho nasezimweni ezinzima. Esinye isithako esibalulekile sokuba nekhono futhi usheshe ekuxazululeni amaphazili e-Futoshiki ulwazi: uma uzijwayeza kakhulu, uzoba ngcono futhi usheshe.

Uma ulungele inselelo, ungadlala iphazili ye-Futoshiki engahleliwe manje ngokuchofoza inkinobho engezansi. Ngikufisela inhlanhla!
