Week 5 Trees W5A1:
W5A1: In this assignment you will demonstrate an understanding of tree structures through the
application of inorder traversal to develop algebraic expressions from existing tree structures and
develop tree structures from given algebra

1. Consider the following binary numbers and convert them to their equivalent hexadecimal
representation. Show all work.
a. 1000 1111 1110 10102
(1000111111101010)2 = (8FEA)16 = 8FEAh
