Hey Naresh,

Make for loop for list and add value in set collection.

Actualy just copying values from list to set isn't correct solution.
From Docs about Set
"Represents a collection of unique elements with no duplicate values."
List can contains duplicate values, Set  not. 
So in FOR loop case you should also do check for set.contains(), so only if it false you can add value to the Set collection

List<Account> accList = new List<Account>
Set<Account> accSET = new Set<Account>
For(Account acc : accLIst) {
  accSet.add(acc) ;
}
