tree-max
- write a function to find the maximum value stored in the tree. You can assume that the values stored in the Binary Tree will be numeric.
 
Whiteboard Process

BIG O_____
- the time complexity is O(n)
 
Solution
- 
    
make a for loop to iterate on the list returned from the inorder function in Binary Tree class and declare a variable to zero then check if the rotated number is greater than the variable assigned to it if it is greater assign it to the last variable.
