Question $1$: Binary Trees. Given the postorder and inorder traversal of a binary tree, construct

the binary tree and output its preorder traversal. Then given two binary trees, determine whether

it is a subtree of the other binary tree. A subtree of a tree $T$ is a tree consisting of a node in $T$ and

all of its descendants in T$.$ For example, the second tree is a subtree of the first tree.
