c# - ASP.NET: Remove specific item in Dropdownlist - i'm doing code time start , time end. did manual coding. here's illustration gui: its hh:mm value hr 00 - 23 minutes 00 - 59 scenario: my start time 8:00 [8-hour,00-minutes], have autopostback. end time of hr not display 00-07 hr display number 8 23. here's code: int _intdiff = _tmrstart - _tmrend; (int x = 0; x <= _intdiff; x++) { dropdownlist3.items.remove(dropdownlist3.items[x]); } its working displaying wrong output.. here's illustration output: as can see there, programme removes number 00,02,04,06,08. how can create staring 00 - 07 remove in dropdownlist? if iterate through forwards first element removed on first iteration 00. on sec iteration sec element removed, no 02 01 has moved first element. need iterate backwards elements removed lastly 1 first. try: for (int x = _intdiff -1; x > -1; x--) { dropdownlist3.items.remove(dropdownlist3.items[x]

node.js - Using Passport to authenticate based on dynamic route - i'm building api node.js, , have endpoints want secure. for simplicity let's assume i'm using http basic authentication ( passport-http ) of endpoints. what i'd on top of that, create sure route this: api.example.com/users/:uid/ accessible user id. i can this: app.get('/users/:uid', passport.authenticate('basic', { session: false }), function (req, res, next) { if (req.params.uid !== user.id) { homecoming next(new error('unauthorized')); } homecoming next(); }, function (req, res, next) { // secret stuff } ); but wonder if there's way without adding additional middleware, using passport itself: app.get('/users/:uid', passport.authenticate( ??? ), function (req, res, next) { // secret stuff } ); is possible? if not, there improve way?

algorithm - Communication complexity - i sending strings server , want calculate complexity. for each string s sending prefices of s . hence start sending 1 character, 2 characters, 3 ... until sending |s| characters. what communication complexity here? have said o(|s|²) not certain. also in algorithm sending each character in s fix-sized amount of data, let's 100 characters. sending |s| * 100 characters. should in o(|s|) right? 1 worse? short s first algorithm better, or off here? please, right me if wrong. sending 1 character, 2 characters, 3 ... until sending |s| characters. when send first character, remaining charcters (|s|-1) or starting 1 time again everytime |s| for first possibility: let's |s|=n 1+2+...+n=n(n-1)/2 the complexity in case is: o(|s|^2) for sec possibility: 1+2+...+a=|s| the complexity in case is: o(|s|) linear-time complexity time better, check tutorial more info complexity time algorithm co
