Vishnu_SFDC Iterate through the list and compare each element with every other element.
To achieve this i am using two for loops which is a bad approch. can any one suggest me a better approch than this.
for example: if i compare slot[10] and slot[11] and i remove slot[11], i also have to compare slot[10] and slot[12] which is not happening in below code without using extra for loop.

hanks for your help.

slots.remove(i+1);

map<date,list<slots>> mapSlot= new map<date,list<slots>>();
for(integer i=0;i<=slots.size()-2;i++)
{
if( !mapSlot.containskey(slots[i].StartDateTime))
{
list<slots> listSlots= new list<slots> ();
mapSlot.put(slots[i].StartDateTime,listSlots);
}
VerifiyData (mapSlot,slots[i]);
}
// this method to put your business logic inside.
private void VerifiyData( map<date,list<slots>> mapSlot ,slots slot1 )
{
if(mapSlot.size() ==0)
{
mapSlot.get(slot1.StartDateTime).add(slot1);
}
else
{
list<slots> listSlots= mapSlot.get(slot1.StartDateTime);
foreach (slots slt :listSlots)
{
// put your logic here and verify slot1 with the listSlots and remove from the object listSlots the unwanted value
}
}
}
and once you are done you will have a map that contains the correct data.
