unexpected output in nested list

Hi All,

I trying to print nested list using system.debug().
Output in log : ((1,2,5),(already output))
expected      : ((1,2,5),(1,2,5))

when i iterate to list i am getting expected outputs. 
just want to know why it is showing "already output" in debug log?

I am assuming (already output) comes up when the same object is being debugged (printed) twice in the same statement. In your case, the list 'inside' is being added to the parent list 'test' twice and is printed.
In any case, you can iterate through the list to have the individual values 
List<Integer> inside = new List<Integer>{1,2};
List<List<Integer>> test = new List<List<Integer>>();
test.add(inside);
inside.add(5);
test.add(inside);
System.debug(test[1]);
System.debug(test);
for(List<Integer> lst : test){
    System.debug(lst);
}

Thanks,
Satish Kumar
