django - Itinerary Not rendered With directionsDisplay.setDirections(result) in Javascript -


i try render itinerary in javascript using variable django model. can render single location itinerary... doesn't work... basicaly use geocode function convert input address geometry location when use these coordinates doesn't show anything...

here code, if can me great!

    <script> var directionsdisplay; var directionsservice = new google.maps.directionsservice(); var map;  function initmap() {  directionsdisplay = new google.maps.directionsrenderer();  var mapoptions = {     zoom:12,     center: {lat: 0, lng: 0},     maptypeid: google.maps.maptypeid.roadmap   }   map = new google.maps.map(document.getelementbyid('map'), mapoptions);   directionsdisplay.setmap(map);   var geostart = new google.maps.geocoder();   var startpos;   var start = document.getelementbyid('addrloc').value;   geostart.geocode({'address': start}, function(results, status) {             if (status === 'ok') {              startpos = results[0].geometry.location;             } else {               alert('address has not been found');             }           });   var geoend = new google.maps.geocoder();   var endpos;   var end = document.getelementbyid('addrdest').value;   geoend.geocode({'address': end}, function(results, status) {           if (status === 'ok') {            endpos = results[0].geometry.location;           } else {             alert('address has not been found');           }         });   var request = {     origin: startpos,     destination: endpos,     travelmode: 'driving'   };   directionsservice.route(request, function(result, status) {     if (status == 'ok') {       directionsdisplay.setdirections(result);     }   }); } </script>

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...
