Science, mathematics and technology are different because engineering has to do with physical work and you can't get the measuring on a jet or a plane wrong because it could fail in mid air. As for math and science if you fail the test, then you can always re-do it.
Answer:
Option (A)
Explanation:
In the post order traversal, we always print left subtree, then right subtree and then the root of the tree. In preorder traversal, First the root is printed, then, left subtree and at last, right subtree, so, the first element in preorder is the root of the tree and we can find elements of left sub tree from in order as all the elements written left to the root will of left subtree and similarly the right one. This is how repeating it will give the post order traversal.
