  1. In this question, you have given a sequence of numbers and you have to build a BST from it.
    Then you have to print the preorder traversal of the BST you have created.
  2. You are given two number a & b and you have to print all the numbers present in the BST (say x) and lies in the range [a,b] i.e. a<=x<=b.
