1) At first we toast 1st and 2nd pieces from bottom side ----------> time spent 1 minute.
2) now toast 1st and 3rd piece , 1st piece from upper side and 3rd piece from bottom side ----------> time spent 1 minute.
3) now toast 2nd and 3rd piece , 2nd piece from upper side and 3rd piece from upper side ----------> time spent 1 minute.
so total time spent 3 minute.
