Sau qhov kev pab cuam los tsim Powerset ntawm ib qho teeb tsa hauv Java. Lub hwj chim teeb ntawm ib lub teeb S yog lub set ntawm tag nrho cov ua tau subsets ntawmS, nrog rau lub khoob teeb thiab S nws tus kheej.
Koj tsim PowerSet hauv Java li cas?
Define ib txheej tshiab hauv java: Teeb teeb=tshiab HashSet; // txhais ib pawg integers hauv java. Set< Set > setOfSets=tshiab HashSet; // PowerSet is a set of sets..
Power Set with Java
- Nrhiav thawj subset - piv txwv li, lub khoob khoob.
- Ntxiv rau cov subsets twb pom.
- Ntxiv txhua yam khoom los ntawm thawj txheej rau.
Koj ua PowerSet li cas?
Yuav kom tsim tau lub zog teeb, saib seb koj tsim lub subset li cas: koj mus rau txhua lub ntsiab lus ib los ntawm ib qho, thiab tom qab ntawd khaws nws lossis tsis quav ntsej nws. Cia qhov kev txiav txim siab no qhia los ntawm me ntsis (1/0). Yog li, txhawm rau tsim {1}, koj yuav xaiv 1 thiab poob 2 (10).
Lub zog teeb tsa hauv txoj hlua yog dab tsi?
Power Set Power set P(S) of a set S is the set of all subsets of S. Piv txwv li S={a, b, c} ces P(s)={{}, {a}, {b}, {c}, {a, c}, {b, c}, {a, b, c}}.
Lub zog teeb nrog piv txwv yog dab tsi?
Ib lub zog teeb yog txhais raws li set lossis pab pawg ntawm tag nrho cov subsets rau ib qho twg muab, suav nrog cov teeb tsa khoob, uas yog qhia los ntawm {}, lossis, ϕ. Ib txheej uas muaj 'n' ntsiab muaj 2 subsets hauv txhua qhov. Piv txwv li, cia Teem A={1, 2, 3}, yog li ntawd, tag nrho cov ntsiab lus hauv lub teeb yog 3.
