  (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 delete the maximum value of a binary tree.
  2. Write a function to calculate the sum of all the leaf nodes of a given binary tree.
  3. Write a function to delete duplicate entries from a binary tree
  4. Write a function to delete the root node of a tree and replace with the right-most leaf node. (Hint. Write another function to delete the right-most leaf node first!)
  5. Write a function to build a binary tree from a given array of int.
  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.
