sao

i use array to storage the nums, and i successed in my chorme,but can't in here; lose heart!!!,this my code ,who can help me?
var ll=[];
function intCubeSumDiv(n) {
// your code
if(ll.length!=0){
if(ll.length>=n){
return ll[n];
}else{
return test(ll[ll.length-1],n);
}
}else{
return test(2,n);
}
}
function test(w,n){
var sum=0;
for(var j=1;j<=Math.sqrt(w);j++){
if(w%j==0){
if(j==Math.sqrt(w)){
sum+=j;
}else{
sum+=j+w/j;
}
}
}
if(Math.pow(w,3)%sum==0){
ll.push(w);
if(ll.length==n){
return w;
}else{
w++;
return test(w,n);
}
}else{
w++;
return test(w,n);
}
}

cool solution
