CSE331 Section 2 Homework 5 (Updated Feb. 20)
Due: Friday Feb. 22, 2008 at 11:59am
1.
Discuss the relationship between an expression tree and the sequence generated
by a tree traversal:
a.
Draw a binary expression tree for each of two following two sequences.
Preorder:  * a + b c / d e
Inorder: c + d * a  b  e
b.
Describe the methods you used to construct the two trees above.
c.
Given any valid preorder sequence, is the corresponding binary expression
tree unique?
If yes, prove it.
Otherwise, give a small counterexample.
(NOTE:
The
proof
of part (c) is now
optional
.
You should state whether
a preorder sequence is unique, but you do not have to prove it either way)
d.
Given any valid inorder sequence, is the corresponding binary expression
