Flat data to hierarchical data ?

hi,

i convert flat arraycollection hirarchical one.

the flat data 1 :

a= []
a[0].id = 0;
a[0].parentid= 0;
a[0].label = 'root';
a[1].id = 1;
a[1].parentid= 0;
a[1].label = 'second';
a[2].id = 3;
a[2].parentid= 1;
a[2].label = 'second.first';
a[4].id = 4;
a[4].parentid= 1;
a[4].label = 'second.second';
a[5].id = 5;
a[5].parentid= 4;
a[5].label = 'second.second.first';

any idea ?
