Some popular operations are printList and makeEmpty, which do the obvious things; find, which returns the position of the first occurrence of an item; insert and remove, which generally insert and remove some element from some position in the list; and findKth, which returns the element in some position (specified as an argument). If the list is 34, 12, 52, 16, 12, then find(52) might return 2; insert(x,2) might make the list into 34, 12, x, 52, 16, 12 (if we insert into the position given); and remove(52) might turn that list into 34, 12, x, 16, 12.
