An warware: tuple zuwa jeri

Tabbas, na fi shirin rubuta koyawa na Haskell Tuple zuwa Lissafi. Gashi nan:

'Yan bulolin wani muhimmin al'amari ne na Haskell programming language. Suna samar da hanya mai sauฦ™i don adana ฦ™ima mai yawa tare a cikin tsari ษ—aya, amma ba kamar lissafi ba, waษ—annan dabi'u na iya zama nau'i daban-daban. Koyaya, wani lokacin zaku iya gano cewa tuple ba shine mafi kyawun tsari don buฦ™atun ku ba, kuma kuna son canza shi zuwa jeri. Wannan labarin zai zurfafa zurfin yadda ake canza tuple zuwa jeri a Haskell.

A canji-zuwa-jeri na iya zama aiki mai amfani a Haskell amma yana buฦ™atar mahimmancin fahimtar duka jeri da fasalulluka a cikin Haskell. Tare da wannan daga hanya, bari mu nutse cikin mafita.

tupleToList :: (a, a) -> [a]
tupleToList (x, y) = [x, y]

A sama akwai aikin Haskell mai sauฦ™i wanda ke ษ—aukar tuple (x, y) kuma yana fitar da shi azaman jeri [x, y]. Wannan aikin yana biye da daidaitaccen ma'aunin Haskell don ma'anar aiki. Ya ฦ™unshi sunan aikin (tupleToList), sigogin aikin ((x, y)), aikin dawowa (=), da jerin da aka dawo ([x, y]).

Fahimtar Lissafin Haskell

Lissafin Haskell tsarin bayanai ne masu kama da juna, wanda ke nufin kowane abu a cikin jerin dole ne ya kasance nau'in iri ษ—aya. Sabanin haka, tuple tsarin bayanai ne daban-daban, wanda ke nufin cewa tuple na iya ฦ™unsar abubuwa da yawa na nau'ikan iri daban-daban.

Maษ“alli mai mahimmanci na lissafin a cikin Haskell shine cewa suna recursive data Tsarin. Ana iya ayyana jeri azaman jeri mara komai ko hade da wani abu da jeri. Wannan ma'anar maimaitawa yana sa lissafin dacewa sosai don ฦ™irar algorithm mai maimaitawa.

Binciken Haskell Tuples

Tuples a cikin Haskell suna yin maฦ™asudi daban-daban. Ba kamar lissafin ba, suna tattara fagage da yawa na nau'ikan iri daban-daban zuwa ฦ™ima ษ—aya. ฦ˜irar su ta fi don ฦ™irฦ™irar nau'ikan bayanai masu sauฦ™i da tara ฦ™ididdiga masu alaฦ™a da aka haษ—a su cikin raka'a ษ—aya.

Wani muhimmin bambanci tsakanin jerin Haskell da tuples shine cewa tuples baya buฦ™atar zama kama. Wato - tuples na iya ษ—aukar bayanai iri daban-daban sabanin lissafin da ke riฦ™e da bayanai iri ษ—aya kawai.

Yin la'akari da waษ—annan nau'o'in tuples da jeri, yana da sauฦ™i a ga dalilin da yasa mutum zai so ya canza daga tuple zuwa jerin a cikin lambar Haskell.

Don taฦ™aitawa, wannan koyawa ta nuna yadda ake ฦ™irฦ™irar aikin Haskell mai sauฦ™i don canza tuple zuwa jeri. Hakanan ya zurfafa cikin halayen duka Haskell tuples da lissafin. Fahimtar waษ—annan fasalulluka yana da fa'ida, musamman lokacin da buฦ™atar canzawa tsakanin waษ—annan tsarin bayanai biyu ta taso. Yanzu, ci gaba da gwaji da Ayyukan Haskell na musamman kuma za ku sami damarsa ta zama abin ban sha'awa mara iyaka da ฦ™arfi sosai.
