Consider the following C program segment
struct CellNode{
struct CellNode *leftChild;
int element;
struct CellNode *rightChild;
};
int Dosomething (struct CellNode *ptr) {
int value = 0;
if (ptr ! = NULL)
{ if (ptr - > leftChild ! = NULL)
value = 1 + DoSomething (ptr - > leftChild);
if (ptr - > rightChild ! = NULL)
value = max(value,1 + DoSomething (ptr - > rightChild));
}
return (value);
}
The value returned by the function DoSomething when a pointer to the root of a non-empty tree is passed as argument is2

A program takes as input a balanced binary search tree with n leaf nodes and computes the value of a function g(x) for each node x. If the cost of computing g(x) is min{ no. of leaf-nodes in left-subtree of x, no. of leaf-nodes in right-subtree of x } then the worst-case time complexity of the program is
