1. Write a program given two binary trees, A and B, searches Tree B for an occurrence of Tree A by shape not by the contents of the nodes. Print all nodes in Tree B that are roots for a subtree whose shape is the same as Tree A. The test is if Tree A could be lifted and moved, its nodes would exactly fit over a subset(s) of nodes in Tree B. In the example below the shape of Tree A appears 3 times in Tree B. The occurrences start at nodes H, G and K. TREE A TREE B Input will be from the keyboard and will consist of 2 strings of letters on separate lines. The first string will be used to construct Tree A. The second string will be used to construct Tree B. Output to the screen all nodes in Tree B that are roots for a subtree whose shape is the same as Tree A with one space between each letter. Multiple nodes may be printed in any order. If none exists, then print NONE. Use a tree data structure. Refer to the sample output below.

I need help writing this program in JAVA

1. Write a program given two binary trees, A and B, searches Tree B for an occurrence of Tree A by
shape not by the contents of the nodes. Print all nodes in Tree B that are roots for a subtree whose
shape is the same as Tree A. The test is if Tree A could be lifted and moved, its nodes would exactly fit
over a subset(s) of nodes in Tree B. In the example below the shape of Tree A appears 3 times in Tree B.
The occurrences start at nodes H, G and K.

B
H
M
TREE A
TREE B
Input will be from the keyboard and will consist of 2 strings of letters on separate lines. The first string
will be used to construct Tree A. The second string will be used to construct Tree B. Output to the
screen all nodes in Tree B that are roots for a subtree whose shape is the same as Tree A with one space
between each letter. Multiple nodes may be printed in any order. If none exists, then print NONE. Use a
tree data structure. Refer to the sample output below.
