my program involves drawing card deck, adding value of hand , deleting card deck (since don't want draw same card twice). example of card: card = ["4 of clubs", 4] the code doesn't work: card_number = random.randrange(len(deck_cards)) card = deck_cards[card_number][0] print(card) hand_value += deck_cards[card_number][1] deck_cards.remove(card_number) i have no idea doing wrong, , if change code to card_number = random.chioce(deck_cards) it won't accept card = deck_cards[card_number][0] part. what do? list.remove takes object, not index, parameter. so should modify code retrieve card , use directly: >>> card = random.choice(deck_cards) # retrieve object, not index >>> print (card) # card card list, i.e.: ["4 of clubs", 4] >>> print (card[0]) 4 of clubs >>> hand_value += card[1] >>> deck_cards.remove (card) note can delete object @ specified index using del built-in: >&

given array contains number of objects, how cleanly , safely first 3 elements out of store in new array? if array not contain @ least 3 elements, should not trigger runtime exception, instead should add number of elements in array new array. i thought might work, won't compile in xcode 7, , if did don't imagine behave safely desire: let arr1 = [1, 2, 3, 4, 5] let arr2 = arr1[0..<3] //expected: arr == [1, 2, 3] let arr1 = [1, 2] let arr2 = arr1[0..<3] //expected: arr2 == [1, 2] let arr1 = [int]() let arr2 = arr1[0..<3] //expected: arr2 == [] of course 1 this, or use loop, neither clean , concise. want find swiftier way. let arr1 = [1, 2] var arr2 = [int]() if photos.count > 0 { arr2.append(arr1[0]) } if photos.count > 1 { arr2.append(arr1[1]) } if photos.count > 2 { arr2.append(arr1[2]) } i think simplest way be let arr2 = arr1.prefix(3)

i have div multiple dropdowns. dropdowns doesn't have id. working other logic remove , add dropdowns within div. if remove dropdown means changes doesn't affect in same script. $(document).ready(function () { $(function () { alert($('#show_lable_categories').find('select').length)); // return 5 //now remove dropdowns $('#show_value_categories').find("select").slice(2).remove(); alert($('#show_lable_categories').find('select').length)); //always return 5 //i need 3 instead of 5 in script }); }); $('#show_value_categories').find("select").slice(2).remove(); i think issue might made typo on element selecting, changes $('#show_value_categories') $('#show_lable_categories'). also tip, want have variable such as: var dropdown = $('#show_value_categories') to avoid bugs such these not have find same element twice.

how can list specific constraint result unsat core? have lot of conditions , printing whole core doesn't print all. read can done assert_and_track , unsat_core commands. found examples don't works. experience this? s.assert_and_track(a > b, 'p1') s.assert_and_track(b > c, 'p2') if s.check() == sat: print('ok') else: c = s.unsat_core print(c) <- print core so how print p1 or p2 (just true/false result) ? e.g. p2 = false, or can displayed in way displayed in print(c) mode - p1. the easiest way achieve save map of labels constraints, examples can m = {} m['p1'] = (a > b) m['p2'] = (b > c) m['p3'] = (c > a) so later can print core in terms of constraints, instance follows core = s.unsat_core() e in core: print(m[str(e)]) of course work if want print entries instead of of them.

i need save permanently big vocabulary , associate each word information (and use search words efficiently). better store in db (in table , let dbms make work of structuring data based on key) or better create trie data structure , serialize file , deserialize once program started, or maybe instead of serialization use xml file? edit : vocabulary in order of 5 thousend 10 thousend words in size, , each word metadata structured in array of 10 integer. access word frequent (this why thought trie data structure have search time ~o(1) instead of db use b-tree or search ~o(logn)). p.s. using java. thanks! using db better. many companies merged db, erp divalto using serializations , merged db performance you have many choices between dbms, if want see data in 1 file simple way use sqlite . advantage not need server dbms running.

since (clk'event , clk='1') commonly used describe rising edge event of clk signal, have following questions: (1) how understand "and"? mean "then"? (2) how (clk='1' , clk'event)? same above? thanks! "and" means logical "and", in "both of these things should true expression return true". yes, logically equivalent. having said this, should use in scenario rising_edge function, example if (rising_edge(clk)) then . , accompanying falling_edge function work correctly in more scenarios, , more readable.

suppose have function f(n)= log n , function g(n)=log n^2. question f(n)=o(g(n)) or f(n)=big_theta(g(n)). since log n^2 = 2 log n way put question can use fraction constant k? big_theta option, have k1=1/4 lower bound , k2=1 upper bound. okay? obviously, k cannot 0 or negative not sure fraction , did not see clear answer on web or in books looked in. thanks in advance help. both f(n)= Θ(g(n)) , f(n)= Θ(g(n)). please note @ same time true f(n)=o(g(n)). intuitively big-oh means f bounded above g(n)(i.e. grows no faster g). big theta on other hand means f bounded both above , below g(i.e. grows precisely fast g). please note last 2 sentences not absolutely precise purpose of being easier understand , focus on intuitive meaning of rather theory.

suppose have code: class c extends a#b { override def fun(): int = 100 } trait { type b = { def fun(): int } } the compiler says: class type required object{def fun(): int} found class c extends a#b { ^ how can understand error? you cannot extend structural type in scala. structural types denote bunch of methods type has define in order used @ places structural type expected. thus, sufficient write class c { def fun(): int = 100 } to pass objects of type c variables of b .

so trying create random array of 5 elements, elements should filled numbers 1 6 , shall not repeat, can't tell logic wrong. void gennumber(int vet[]){ int max, i, j, atual; srand(time(null)); max = 7; (i=0;i<5;i++){ vet[i] = rand() % max; while(vet[i] == 0){ vet[i] = rand() % max; } for(j=0;j<i;j++){ atual = vet[j]; while((vet[i] == atual)||(vet[i] == 0)){ vet[i] = rand() % max; atual = vet[j]; } } } } update: fixed void gennumber(int vet[]){ int max, i, j; srand(time(null)); max = 7; (i=0;i<5;i++){ vet[i] = rand() % (max-1) + 1; for(j=0;j<i;j++){ while(vet[j] == vet[i]){ vet[i] = rand() % (max-1) + 1; j = 0; } } } } the logical flaw in way produce new random number when duplicate found. imagine have vel = {1,2,0,0,0,...} , trying find number vel[2] . if randomly draw 2 , you'll find it

say i've got state1 has children state1.child1 , state2.child2 . there's state2 has state2.child1 , state2.child2 . there way can put ui-view in state1.child1 view state2.child1 ? the answer no (as expected) . states hierarchical, , same applies views. so, cannot display child of 1 hierarchy in another's hierarchy parent. in case, wanted reduce amount of code (declaring same views , substates in different hierarchies) can use e.g. decorators: angularjs: how set 1 state global parent in ui-router (to use modal common parts) setting view's name decorator - angular ui router
