java - Two overlapping rectangles -

i'm having lot of trouble figuring out wrong code. actually, i'm having difficult time solving problem of 2 rectangles overlapping. following code should, theoretically, work following rectangles: rect1: (2.5, 4) width = 2.5, height = 43 rect2: (1.5, 5) width = 0.5, height = 3 keep in mind can't use rectangle class solve problem. i've done calculated x-values left , right edges , y-values top , bottom edges of both rectangles. i'm first considering -- , know not cover possible cases -- scenario in r2 within r1. note (x1, y1) , (x2, y2) signify centers of rectangles 1 , 2, respectively. right1 = x1 + w1/2; left1 = x1 - w1/2; bottom1 = y1 - h1/2; top1 = y1 + h1/2; right2 = x2 + w2/2; left2 = x2 - w2/2; bottom2 = y2 - h2/2; top2 = y2 + h2/2; overlap = ( (right2 < right1 && right2 > left1) && (bottom2 > bottom1 && bottom2 < top1) && (left2 > left1 && left2 < right1) && (top2 < top1 ...

algorithm - Faster Queries in plane -

problem have support q queries of set of n 2-d points in cartesian plane lying in [0,m]x[0,m]. points given in advance. each query ask me count number of points enclosed in rectangle (x1,y1)*(x2,y2). (axis aligned rectangle). constraints 0 < m < 10000 i want know more algorithms used. can perform these queries more efficiently using information points , queries given in advance , coordinates of points bounded etc. variant : instead of n points begin with, can add n axis-aligned rectangular patches of points n add operation in our data structure , answer same queries. [lazy segment trees kind of approach]. this classic 2d binary indexed tree problem. binary indexed tree can give how many dots in rectangle (0,0) (x,y), if want find out how many dots in rectangle indicated (x1,y1) , (x2,y2), first have find coordinates of other 2 corner points of rectangle. let pul, pur, pbl, pbr 4 corner points of rectangle representing upper left corner, upper right corn...

c# - Generic property-list with any generic argument -

javascript - RxJS the switch function -

could please explain switch function in rxjs do? read documentation not configure out, how works exactly. if have observable stream of observable values, switch flatten nested observable single stream of observable values. feed values recent inner stream produced outer stream. it easier example. have textbox controls data receive ajax query. lets call textbox page number. goal display results of ajax query page user types text box. can use switch construct observable stream of data: function getpagedata(pagenumber) { // return ajax query page return $.ajax("/url?page=" + pagenumber)); } var pagenumbervalue = // observable of page number values coming text box // observable of observables of page data var datastreamofstreams = pagenumbervalue .map(pagenumber => getpagedata(pagenumber); // everytime change pages, "switch" new ajax call // , return results new call. var datastream = datastreamofstreams.switch(); i hope helps. ...

Is Android device's locale based solely on Language setting? -

if device chooses french language, locale automatically set french well? or depend on user's current location? for ios, language , region separate settings while in android, seems choose language not region. comparison: android - chooses french language, locale becomes fr-fr ios - chooses english language, french region, locale becomes en-fr for android there other way retrieve device's region? i have been googling around couldn't find source of information on topic yet. in android can select portuguese (portugal) or portuguese (brasil) translates pt-pt , pt-br. in case there 2 different languages, find redundant, because better way of handling separate languages , regions. however can programmatically change language , region, setting: new locale("pt, "pt"); you can read more programmatically changing language here: http://gunhansancar.com/change-language-programmatically-in-android/ http://www.sureshjoshi.com/mobile/changing-a...

Telnet commands automation through File or String in Java -

i automating telnet commands using apache.commons.net in java. able run program standalone, nature of telnet interactive, how can run telnet commands through file or string variable? there 2 ways handle interactive command-based interface programatically. the simple way: have list of commands, , send 1 after small delay between them. the complicated way: have simple rule-based system, read remote system , matches text against 1 or more rules. depending on matching rule, perform action, sending command. the first way indeed simple, doesn't handle errors or problems well. if there problem, not notice, continuing send commands may make problems worse. the second way in turn implemented simple, reading text remote system, , if doesn't match expect bail. handled simple finite state machine . suitably designed , implemented might able handle connection troubles gracefully.

gradle - Android: Does changing API level to 23 affect the way a permission in the manifest is set up? -

this question has answer here: android permission doesn't work if have declared it 10 answers i not expert in android development please bear me. i change app android 19 23. android api 23 changed way permissions work. happens in api 23 instead of asking permissions in app installation, asks permission on run time. my question need change way permission set in andoid manifest? because tried change api 23 in build.gradle , seems still work no differences. no. targetsdkversion , minsdkversion etc set in code has no effect on how permissions handled, rather dependent on device target app running. android changed way permissions asked in android 6.0(api 24 devices). have make ask permissions @ runtime. official documentation asking runtime permissions user.
