Q4: Is BST Write a function is_bst, which takes a Tree t and returns True if, and only if t is a valid binary search tree, which means that: • Each node has at most two children (a leaf is automatically a valid binary search tree) • The children are valid binary search trees • For every node, the entries in that node's left child are less than or equal to the label of the node For every node, the entries in that node's right child are greater than the label of the node
