Problem 10.1
Comparisons among lists
For each of the four types of lists in the following table, what is the asymptotic worst-case running time fore each dynamic-set operation listed?
unsorted, singly linked | sorted, singly linked | unsorted, doubly linked | sorted, doubly linked | |
---|---|---|---|---|
SEARCH(L, k) |
linear | linear | linear | linear |
INSERT(L, x) |
constant | linear | constant | linear |
DELETE(L, x) |
linear | linear | constant | constant |
SUCCESSOR(L, x) |
linear | constant | linear | constant |
PREDECESSOR(L, x) |
linear | linear | linear | constant |
MINIMUM(L, k) |
linear | constant | linear | constant |
MAXIMUM(L, k) |
linear | linear | linear | linear |
-
MAXIMUM
assumes that we don't keep track of the tail of the list. If it does, we can make the algorithms constant when the list is sorted
