Indlela yokuxazulula izindida ze-Futoshiki ngempumelelo

Kulesi sifundo esilandelayo, amasu ayisisekelo nathuthukile okuxazulula izindida ze-Futoshiki achazwa isinyathelo ngesinyathelo, kanye nemifanekiso ebonisa izindlela ezimweni ezithile zebhodi.

Isiqalo sokufinyelela esixazululweni yincazelo yomdlalo uqobo: i-Futoshiki idinga ukuthi umdlali athole ibhodi lapho idijithi ngayinye ivela kanye kuphela emugqeni nasekholomu ngayinye, ngokulandela izimpawu zokungalingani zebhodi. Ngokusebenzisa lo mbandela, ungasondela esixazululweni ngokugcwalisa, isinyathelo ngesinyathelo, izikwele ezingenalutho ngamadijithi athile, ngoba yiwo kuphela ahambisana nemikhawulo yebhodi.

Ukukhishwa kwekholomu kanye nomugqa

Uma ikholomu nomugqa wesikwele sekuvele kunawo wonke amadijithi angaba khona ngaphandle kweyodwa, leso sikwele kufanele sibe nedijithi eshodayo. Esibonelweni esingenhla, isikwele esiluhlaza kufanele sibe ngu-4, ngoba asivunyelwe ukuba nelinye inani: wonke amanye amadijithi angaba khona asevele asemugqeni waso noma ekholomu yaso.

Uchungechunge lokungalingani

Uma ubona uchungechunge lwezimpawu zokungalingani, kungaba < (konke kukhuphuka) noma > (konke kwehla), olunobude obulingana nosayizi webhodi, lolo chungechunge kufanele lube ukulandelana kusukela ku-1 kuya kubude bebhodi. Ubude bochungechunge buqinisekisa ukuthi lokhu kulandelana kuwukuphela kwesixazululo esingaba khona esanelisa umbandela we-monotone obekwe uchungechunge lokungalingani.

Amanani aphansi naphezulu aphoqelelwe

Izikwele ezingaphansi kuka-2 kufanele ngokuzenzakalelayo zibe nenani elingu-1, ngoba yilona lodwa inani elivumelekile ebhodini elihambisana naleso simo. Ngokufanayo, izikwele ezinkulu kunosayizi webhodi okususwe kuwo u-1 kufanele zilingane nosayizi webhodi. Esibonelweni esingenhla, okuwukuphela kwenani elingaba khona esikweleni esiluhlaza (esingaphansi kuka-2) ngu-1.

Ukukhishwa kwamanani amancane naphezulu

Izikwele ezinkulu kunezinye izikwele azikwazi ukuba ngu-1, inani eliphansi kakhulu elivunyelwe ebhodini, ngoba alikho inani elincane kuno-1. Ngokufanayo, izikwele ezincane kunezinye izikwele azikwazi ukuba nenani eliphezulu elivunyelwe, ngoba ngeke kube khona inani elikhulu ukwedlula lelo elingafakwa ngakolunye uhlangothi lophawu lokungalingani. Esibonelweni esingenhla, u-1 akakwazi ukufakwa ezikweleni ezibomvu ngoba zonke zinkulu kunezinye izikwele zebhodi, ngakho-ke okuwukuphela kwendawo ka-1 emugqeni wokuqala webhodi yisikwele esiluhlaza.

Ukuhlanganisa imithetho

Ngezinye izikhathi kudingeka ukusebenzisa imithetho eminingana ukuze ufinyelele esiphethweni. Kunjalo esibonelweni esingenhla, lapho sizama ukubeka inani elingu-1 emgqeni wesibili webhodi. Isikwele sokuqala esibomvu siyakhishwa ngenxa yokukhishwa kwekholomu (sesivele sino-1 kuleyo kholomu), kanti esesibili nesesithathu ezibomvu zikhishwa ngenxa yokukhishwa kwamanani amancane, ngoba lezo zindawo zinezimpawu zokungalingani ezithi 'kukhulu kuno'. Ngakho-ke isikwele esiluhlaza yisona kuphela indawo engabekwa kuyo u-1 kulowo mugqa.

Ukuhlola amathuba ngamunye

Ngezinye izikhathi, ikakhulukazi emabhodini anzima, ayikho enye indlela yokuthola idijithi efanele yesikwele ngaphandle kokuhlola imiphumela yethuba ngalinye kuze kutholakale ukuphikisana. Esibonelweni esingenhla, zonke izikwele ezibomvu neziwolintshi ekuqaleni azinalutho. Sifuna ukuthola ukuthi isikwele A siqukethe u-1 noma u-2. Sicabanga ukuthi siqukethe u-2 bese sihlola ukuthi lokhu kucabanga kuyasiholela yini ekuphikisaneni.

Uma isikwele A sino-2, isikwele B sizoba no-1 (okuwukuphela kwenani elisele emgqeni ongezansi). Isikwele C singaba ngu-1 noma ngu-2, ngoba sinochungechunge lokungalingani oludinga izinombolo ezimbili ezinkulu kunaso, kodwa manje asikwazi ukuba ngu-1 ngenxa yokukhishwa kwekholomu kwesikwele B, ngakho isikwele C singu-2, kanti isikwele D singu-3 (okuwukuphela kwenani eliphakathi kuka-2 no-4). Ngenxa yokukhishwa kwamakholomu, isikwele E singu-1 kanti isikwele F singu-3.

Manje, uma sibheka izikwele eziwolintshi, sibona ukuphikisana: uma isikwele G besingaba ngu-2, isikwele H besizofanele sibe ngu-3 noma ngu-4, okungavunyelwe ngenxa yokukhishwa komugqa. Uma isikwele G besingaba ngu-3, isikwele H besizofanele sibe ngu-4, okungavunyelwe ngesizathu esifanayo. Njengoba singasenawo amanani asele esikweleni G, kusho ukuthi sifike endaweni engaphumeleli futhi ukucabanga kwethu kokuqala bekungalungile: u-2 akuwona umnyakazo ovumelekile wesikwele A, ngakho singaqhubeka sibeke u-1 kuso, okuwukuphela kwelinye inani elingaba khona.

Iziphetho

Ngenhla sibonise ukuthi ungayixazulula kanjani ngempumelelo indida ye-Futoshiki, ngokuchaza amasu ahlukahlukene angakusiza ukuthi uthole umnyakazo olandelayo ngisho nasezimweni ezinzima. Enye into ebalulekile ukuze ube nekhono futhi usheshe ekuxazululeni izindida ze-Futoshiki ulwazi oluvela ekuzijwayezeni: uma uzijwayeza kakhulu, uba ngcono futhi usheshe kakhulu.

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