A tree can be uniquely determined by specifing its postorder sequence and number of leaves for each node.
Let's consider a tree with the following postorder sequence of its nodes and corresponding number of children:
nodes: J-H-A-E-I-G-K-C-B-F-D
number of leaves: 0-0-0-3-0-0-0-0-3-2-2
(for example, the node E has 3 children and the node G is a leaf)
Which of the following is the preorder traversal sequence of this tree?
D-E-F-H-K-I-F-B-G-A-C
D-I-C-H-A-G-E-B-F-K-J
I-E-A-H-J-F-D-B-G-K-C
D-A-J-H-E-K-I-B-E-F-C
D-E-J-H-A-F-I-B-G-K-C
D-F-J-B-G-E-I-H-A-K-C
A-E-J-F-D-H-B-I-G-K-C
D-E-H-J-A-J-I-B-G-F-C
C-E-K-H-A-J-I-B-G-J-D
A-E-C-H-D-I-F-B-G-K-J
C-G-J-H-A-F-I-B-D-K-D
