For each node, the values of its left descendent nodes are less than that of the current node, which in turn is less than the right descendent nodes (if any). The BST is built on the idea of the binary search algorithm, which allows for ...

For this, We will compare the key with the root node of the tree. If key equals to root node, the key is found. If the value of the key is greater than the root node, take the right subtree and search for the key.
