(A) A binary tree of N external nodes has N internal node
(B) A binary tree of N internal nodes has N+ 1 external node
(C) A binary tree of N external nodes has N+ 1 internal node
(D) A binary tree of N internal nodes has N- 1 external node

(A) O(1) time because all lists take the same amount of time to sort
(B) O(n) time because it has to perform n swaps to order the list
(C) O(n2) time because sorting 1 element takes O(n) time – After 1 pass through the list, either of these algorithms can guarantee that 1 element is sorted
(D) O(n3) time, because the worst case has really random input which takes longer to sort

(A) Each list Si contains the special keys + infinity and – infinity
(B) List S0 contains the keys of S in non-decreasing order
(C) Each list is a subsequence of the previous one
(D) List Sh contains only the n special keys

(A) Sorted
