  (You are responsible to check if your student number is correct!)
  Read carefully the binary tree implementation given in class. Using that given tree structure to dothe following problems:
  1. Write a function to compare two tree if they are the same. The function should return 1 if they are the same, or 0 otherwise.
  2. Write a function to count the number of leaf nodes of a given binary tree.
  3. Write a function to find the predecessor and successor of a given value of a binary tree.Definition : If node X has two children, its predecessor is the maximum value in its left subtree and its successor is the minimum value in its right subtree
  4. Write a function to delete duplicate entries from a binary tree
  5. Write a function that uses pre-order tranversal to place the values of the nodes in an array
    datatype pre_ordered[]
  You must also write a main function with other sufficient function calls to Insert() and Print() and several test cases to make sure your program performs properly! Each program should be in a seperate file with meaningfulcomments for your code. You may re-use as much code as needed for each part.
