javascript - Angular JS fast resolve and slow controller page is empty while the data loads -


i have main.html . name card , system detail going remain constant , content keep on changing depending upon view . 

        <div ui-view="namecard"></div>         <div ui-view="systemdetail"></div>         <div ui-view="content"></div>

im using ui route routing . when switch 1 view other , resolve happens first (the page loads first here), followed controller initialization , loads data . due lazy controller , users left view @ blank page while. , how should add spinner logic user left view @ spinner till data loads. when clicks on button want enable spinner before resolve happens , hide spinner after post has happened .shoud ass in main.html or should add in content page

you can enable spinner on state change 

$scope.$on('$viewcontentloaded', function(){   // add show spinner code here });

and disable when content load 

$scope.$on('$viewcontentloaded', function(){   // add hide spinner code here });

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
