Q3 -
possible approaches -
if the tree is simply - i think we need to store two traversals inorder and
preorder in file.
otherwise in case of BST preorder traversal is sufficient to recreate the
tree.
for general tree - do a breadth first traversal and for each node next to it
put its parent value (assuming repeated values not allowed in tree). while
recreating the tree read two values at a time from file and attach the node
to its parent.
