Write a C program to find the mininum value in a binary search tree.

Here is some sample C code. The idea is to keep on moving till you hit the left most node in the tree

int minValue(struct node* node)
{
struct node* current = node;

while (current->left != NULL)
{
current = current->left;
}
return(current->data);
}

On similar lines, to find the maximum value, keep on moving till you hit the right most node of the tree.
