is there tool out there can check if imported jar being used within package? want remove unused jars project , not want have remove each jar one-by-one , check possible reference issues each removed jar. proguard trick you! configured correctly , given initial rules take jar files in input directory , output same jars output directory. java class files aren't needed won't included in output jars , if jar has no classes left, it's removed. website includes tons of examples . in addition doing this, has number of great features in compacting , obfuscating final project. configuration files may seem bit tricky @ first -- pays off. in projects @ work, have final archive sizes reduced on 1000%. how have included library use fraction of functionality? proper setup final product include what's needed.

i've seen people create objects in c++ using thing mything("asdf"); instead of this: thing mything = thing("asdf"); this seems work (using gcc), @ least long there no templates involved. question now, first line correct , if should use it? both lines in fact correct subtly different things. the first line creates new object on stack calling constructor of format thing(const char*) . the second 1 bit more complex. following create object of type thing using constructor thing(const char*) create object of type thing using constructor thing(const thing&) call ~thing() on object created in step #1

i have program //h our n static int g=0; int fun(int h){ if(h<=0){ g++; return g; } return g+fun(h-1)+fun(h-4); } is possible speed using dynamic programming? i figured out function runs in o(2^n) i supposed reduce running time dynamic programming, not understand concept. just asking nudge in right direction. while can't give answer actual question, intrigued altogether different, namely statement return g+fun(h-1)+fun(n-4); obviously, function has side effect of changing global static variable g . not 100% sure whether return statement's expression evaluates in defined fashion, or whether result might undefined. it might nice exercise think order in function calls executed, , how affects g , thereby function's result.

first let me thought way data storage worked in python object there no need such things pointers. if pass piece of data function function has real piece of data. when exit out of function data passed in have been modified. now working lists , thought if put same piece of data on 2 lists modifying in 1 place modify in other. how can have 1 piece of data on two, or more, different lists? want change data in 1 place , have other change. for example take following: p = 9 d = [] f = [] d.append(p) f.append(p) print 'd',d print 'f',f p = 3 print 'd',d print 'f',f when run output is: d [9] f [9] d [9] f [9] i second set of data 3 doesn't seem work. in thought process did go wrong? there implicit copy operation when putting data onto list? first of all, integers (really, number objects) immutable. there no "modifying" "data". second of all, there in python notion of name binding . when do: p = 9 tw...
