i need list of n positive integers l has properties: for each possible subset s of l , if sum items of s , sum not in l for each possible subset s of l , if sum items of s , sum unique (each subset can identified sum) working example 1: n = 4 l = [1, 5, 7, 9] check: 1+5 = 6 ok 5+7 = 12 ok 7+9 = 16 ok 9+1 = 10 ok 1+7 = 8 ok 5+9 = 14 ok 1+5+7 = 13 ok 5+7+9 = 21 ok 1+5+9 = 15 ok 1+7+9 = 17 ok 1+5+7+9 = 22 ok sums unique -> l ok n = 4 as easy construct sequence, suggest using power series , e.g. 1, 2, 4, 8, ..., 2**k, ... 1, 3, 9, 27, ..., 3**k, ... 1, 4, 16, 64, ..., 4**k, ... ... 1, n, n**2, n**3,..., n**k, ... n >= 2 take, instance, 2 : neither power of 2 sum of other 2 powers; given sum (number) can find out subset converting sum binary representation: 23 = 10111 (binary) = 2**0 + 2**1 + 2**2 + 2**4 = 1 + 2 + 4 + 16 in general case, simple greedy algorithm do: given sum subtract largest item less or equal sum ;

i'm making web requests using afnetworking. subclassed nsurlprotocol , method swizzled override default nsurlsessionconfiguration , add protocol class intercept web requests. when caninit called try print request data, want body , query prints null both. know requests being correctly intercepted don't have body/query data. know why is? how go getting body data? so after doing research found apple docs nsurlrequests body , bodystream: the receiver have either http body or http body stream, 1 may set request. http body stream preserved when copying nsurlrequest object, lost when request archived using nscoding protocol. so, after checking httpbodystream found actual body being stored. had copy input stream, convert data, convert string , print. here's reference on how did that: how convert nsinputstream nsstring or how read nsinputstream

i'm using angular 1.5 , creating custom drop-down. there no elements use ngmodel involved. want able have form know if component dirty, pristine, etc. thinking i'd use ngmodel, directive. however, since there no linking function in component, i'm not sure how this. possible? let's component template this: <div>{{model.value}}</div> my code this: angular.component('mything', { bindings: { model: '=' }, require: '^ngmodel' }) .controller('mythingcontroller', () => { // stuff , things }); i made simple example instead of of code because i'm not sure begin using ngmodel within component. didn't think served have me code dump. if more code required, please feel free ask , i'll happily expand example. i created simple pen try work through this: http://codepen.io/yatrix/pen/rwejyv?editors=1011 you can use require: { ngmodel: '^ngmodel' } on component declaratio

i have match function not working. boiled down point can't find appropriate match since values not same, apparently. i have value 21337 in cell d59. in cell s59 have function: right($d59;5), displays 21337. when enter in cell: =d59=s59 return false. i use right() function because cells in column d contain concatenated values, last 5 values of importance. example d60 contains 21337 - 21448, 21448 value want match. anyone has clue on might problem? with no formatting you'll see 21337 right aligned - showing number , treated number excel. on other hand right($d59;5) show number left aligned, indicating returned value being treated text excel. if try right($d59;5)*1 excel implicitly convert value number (due calculation performed) , both values equal. to explicit conversion, brian has pointed out, use value(right($d59;5)) .

im trying make responsive voice read out each sentences , there must 1 minute gap between each readouts. function read(){ responsivevoice.speak('قلم','arabic female'); } var = [1,2,3]; $(a).each( function(){ settimeout(function(){ read(); }, 1000); }); currently plays once , in other 2 loops getting error uncaught (in promise) domexception: play() request interrupted call pause(). i can't make read passed dynamically maybe problem used .each() method not correctly because $(a) try target selector not array. from jquery.each() doc : jquery.each( array, callback ) where array : type: array - array iterate over. callback : type: function( integer indexinarray, object value ) - function executed on every object. so, try this: $.each( a, function(){ settimeout(function(){ read(); }, 1000); }); hope you.

is there way force internet explorer , edge use particular favicon address bar/tab icon? in general i'm using different design (with wider margin) "live tile" (or whatever microsoft calls them)... , reason these browsers keep choosing 1 of images (defined in browserconfig.xml or 1 of apple icons... not sure) use in address bar. this not want, because 1 in address bar/tab icon needs have smaller margin , transparent background. is there safe , consistent method "use icon address/tab bar icon", , "use icon tile or whatever?" edit: acceptable workaround if there way specify images background/margin used "tile" others favicon(s) only? don't understand logic ie/edge use choose icon display. the favicon package generated realfavicongenerator behaves way want: in tabs, edge picks classic "desktop" icon, while uses tile icons sites added home screen. more precisely, edge using classic 32x32 png icon tab ic
