i've got assignment computer science class. i've been thinking answer more 2 weeks without success decided give try in here. game consists of 4 cia agents using 4 adjacent telephone booths. arrive @ set of booths 1 @ time, following rules: 1 - agent chooses booth has 2 neighbouring booths unoccupied (this includes booths @ edges of set); 2 - if condition above isn't met, agent chooses booth has 1 neighbouring booth unoccupied; and 3 - if both conditions fail, agent chooses booth. there 8 different ways of occupying booths given 4 agents , 4 booths, according rules. example: agent #1 occupies first booth (the left edge one), agent #2 occupies third booth (from left right), agent #3 occupies fourth booth , agent #4 occupies second booth. we asked write code counts number of ways 19 agents occupy 19 booths, according these rules. my natural choice problem creating array of boolean, in false represents vacant booth , true represents occupied booth: public...

maybe missing very obvious here: i wanted test packagemanager.getinstallerpackagename() . when test app through eclipse, or standalone apk, above method returns null expected. users install through google play or amazon appstore , returned value not null . my question how test before putting app production? ( eg. possible: upload draft in android developer console, , without moving production, somehow access through google play, maybe using device setup same account developer console account; , install , test on test device?) updated answer: if want able test actual install google play use alpha , beta programs. see here description of program. original answer: if want test handling of case, can use buildconfig.debug flag give dummy value when in debug mode. string installer; if (buildconfig.debug) { installer = "com.android.vending"; } else { installer = pm.getinstallerpackagenamge(mypackage); }

i'm trying learn javascript , dom. based on examples on internet have created html: <input type="text" id="amount3"> then later in javascript code have line. document.getelementbyid("amount3").value= x; the code works well. i'm able change what's shown inside text input. i'm trying understand underlying code , how works. looked dom reference in https://developer.mozilla.org/en-us/docs/web/api/document.getelementbyid . i can see method should return object element . however, element not contain property called value. notice there sub-object called htmlelement has sub-object htmlinputelement. , object contains property called value. is code above somehow typecast child object? why value property work such? htmlinputelement inherits htmlelement which, in turn, inherits element . if object inherits object, have properties of object. this means expects deal element can given htmlinputelement instead (since ...
