i've got solve task can't find answer: compute x | y using ~ , & maximum allowed operations 8 edit: in twos complement , 32-bit representations of integers. right shifts performed arithmetically. by looking @ truth table of x | y see: 0 | 0 = 0 0 | 1 = 1 1 | 0 = 1 1 | 1 = 1 x | y 1 if both x , y not 0 . can translate ~(~x & ~y) : ~(~0 & ~0) = ~(1 & 1) = ~1 = 0 ~(~0 & ~1) = ~(1 & 0) = ~0 = 1 ~(~1 & ~0) = ~(0 & 1) = ~0 = 1 ~(~1 & ~1) = ~(0 & 0) = ~0 = 1

our team has solution has 15 projects work on collaboratively using git source control. when switching branches visual studio updates source files , branch switch takes seconds(bounded how fast can type commands). other times though, when switching branches, visual studio popup dialog saying needs reload projects , have sit , wait approximately 5 minutes while visual studio goes through process. i'm guessing we're doing line endings causing touch 1 of visual studio specific files, , causes reload, i'm not sure one, or if that's right path go down. so specific question is, "what causes visual studio need reload projects?" in fact quite easy: every file change cause visual studio reload file, whether has changed, or not. when changing project file, reload entire project. maybe git, or other software, updating attributes of file (so not content). might trigger 'visual studio' file change monitor already. have same issue using tort...

could please explain me why result here is: dvd unknown dvd:dvd using system; class program { class m { internal string n; internal m() { } internal m(string n) { console.write(n + " "); n = n; } } class d : m { internal d(string n) : base(n) { n = "dvd:" + n; } } static void main(string[] args) { m d1 = new d("dvd"); m m1 = new m("unknown"); console.writeline(" " + d1.n); } } i understand parts of code, except line: internal d(string n) : base(n) { n = "dvd:" + n; } i know base calls parent class, in case don't it. :/ let's break apart line: internal d(string n) : base(n) { n = "dvd:" + n; } the part you're needing clarification on base(n) . base(n) call m(string n) constructor. happens before body of constructor ( n = "dvd... ) r...
