serialize:
pre-order unambiguous form:
(r (r_left) (r_right (r_right_l) ()))
a recursive implementation is much easier than iterative version.
de-serialize:
scan from left to right, use stack for temporary recording, when ')' is
encountered, pops to the previous '(' and generate node accordingly.
2) binary graph
what is the definition of a binary graph? |
