i wanted know if answers indeed correct following statements: 3(n^3) + 5(n^2) + 25n + 10 = bigomega(n^3) -> t ->grows @ rate equals or slower 3(n^3) + 5(n^2) + 25n + 10 = theta(n^3) -> t -grows @ rate equals 3(n^3) + 5(n^2) + 25n + 10 = bigo(n^3) -> t -grows @ rate equals or faster thanks!!! formal definitions of o notations are: f(n) = o(g(n)) means there exists constant c , n0 f(n) <= c*g(n) n >= n0. f(n) = Ω(g(n)) means there exists constant c , n0 f(n) >= c*g(n) n >= n0. f(n) = Θ(g(n)) means there exists constants c1 , c2 , n0 f(n) >= c1*g(n) , f(n) <= c2*g(n) n >= n0. proof o: 3(n^3) + 5(n^2) + 25n + 10 < 3*n^3 + n^3 + n^3 = 5*n^3 you can see n >= 10 formula true. there exists c = 5 , n0 = 10 , o(n^3) . proof Ω: 3(n^3) + 5(n^2) + 25n + 10 > 3*n^3 so c = 3 , n0 = 1 , Ω(n^3) . because both o , Ω apply 3rd statement Θ true.

what class implements interface listiterator ? i'm studying collections api.. , seem though actual method returns listiterator within list implementation classes directly specified in list itself. the listiterator interface specifies actual methods use manipulate iterator.. having trouble finding actual class implements this. what class -implements- interface listiterator allows method in list classes work? i'm sure there has implementation class because calling listiterator() surely can not return interface, there must instantiated. you can't instantiate interface , can create "invisible" private class , satisfying interface , user can't directly see it. example, linkedlist defines listiterator as: public listiterator<e> listiterator(int index) { checkpositionindex(index); return new listitr(index); } private class listitr implements listiterator<e> { private node<e> lastreturned; private node...

if want read file multiple times command ./run in.txt , there straight way... 0- ofstream fin; 1- while (fin >> i) {...} 2- fin.clear(); fin.seekg(0); 3- while (fin >> i) {...} however, want pipe zipped input file program. command is bzcat file.bz2 | ./run and in code, instead of ofstream fin , have use std::cin . while (std::cin >> i) {...} the loop terminates when bzcat sends last line program. now... question is, how can go start position , tell bzcat please send lines 1 more time (form first end) , catch them std::cin ?! the pipe contents consumed read, need retain values in memory if need multipass algorithm, can uncompress , run on file or else can split program multiple stages , run them 1 after other: // 1 std::vector<int> data; std::copy(std::istream_iterator<int>(std::cin), std::istream_iterator<int>(), std::back_inserter(data)); // operate on data #2 $ bunzip2 file.bz2 && ./run file.b...

i have base trait trait mybase { type m type t <: table[m] val query: tablequery[t] } where tablequery scala.slick.lifted.tablequery my subclasses instantiate tablequery so: type m = account type t = accountstable val query = tablequery[t] i'd instantiate tablequery in base trait, possibly using lazy val , i.e. lazy val query: tablequery[t] = { ... } i've been playing around reflection, haven't had luck. if understand correctly, want able extend mybase defining m , t without having explicitly instantiate tablequery in each derived class. using reflection not option because use tablequery.apply (as in val query = tablequery[mytable] ), , implemented through macro, you've got "runtime vs compile-time" issue. if absolutely need mybase trait (as opposed class), don't see viable solution. if can turn mybase class and turn m , t type parameters (instead of abstract types), there @ least 1 solution. hinted...
