The space is given by S 0 (n) = S(n1/c ) + n1/c · S 0 (n1−1/c ) = n(c−1)/c + n1/c · S 0 (n1−1/c ). In the recursion tree, the bottom level dominates, and it has ...

... A doubly linked list is one where each node has two pointers – one points to the next node, and one points to the previous node. The "next" pointer for the last node points to NULL, as does the "previous" pointer for the first node. Suppose you are given a class List, which contains a linked structu ...
