Tree Maximum element
Execution time limit is 1 second
Runtime memory usage limit is 128 megabytes
Binary search tree is given. Return the pointer to the maximum element.
Definition of a tree:
// Java
class TreeNode
{
public:
int val;
TreeNode left;
TreeNode right;
TreeNode(int x) {
val = x;
left = NULL;
right = NULL;
};
// C++
class TreeNode
{
public:
int val;
TreeNode *left;
TreeNode *right;
TreeNode(int x) : val(x), left(NULL), right(NULL) {}
};
Implement function Maximum that returns pointer to the element with maximum value in the tree.
// Java TreeNode Maximum(TreeNode tree)
// C++ TreeNode* Maximum(TreeNode *tree)
Example
Function Maximum returns pointer to the node with value 16 - the vertex with maximum value in the tree.
