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 childrennodes: F-J-D-H-E-G-K-C-I-B-A number of leaves: $0-1-0-0-3-0-0-0-3-1-2$
(for example, the node $\mathrm{E}$ has 3 children and the node $\mathrm{G}$ is a leaf)
Which of the following is the preorder traversal sequence of this tree?
C-G-J-H-A-F-I-B-D-K-D
D-I-C-H-A-G-E-B-F-K-J
A-E-J-F-D-H-B-I-G-K-C
D-E-J-H-A-F-I-B-G-K-C
I-E-A-H-J-F-D-B-G-K-C
D-E-F-H-K-I-F-B-G-A-C
D-F-J-B-G-E-I-H-A-K-C
D-E-J-H-A-F-I-B-G-K-C
I-E-A-H-J-F-D-B-G-K-C
D-E-F-H-K-I-F-B-G-A-C
D-F-J-B-G-E-I-H-A-K-C
D-E-H-J-A-J-I-B-G-F-C
C-E-K-H-A-J-I-B-G-J-D
D-A-J-H-E-K-I-B-E-F-C
A-E-C-H-D-I-F-B-G-K-J
