Answer:
Each time you insert a new node, call the function to adjust the sum.
This method has to be called each time we insert new node to the tree since the sum at all the
parent nodes from the newly inserted node changes when we insert the node.
// toSumTree method will convert the tree into sum tree.
int toSumTree(struct node *node)
{
if(node == NULL)
return 0;
// Store the old value
int old_val = node->data;
// Recursively call for left and right subtrees and store the sum as new value of this node
node->data = toSumTree(node->left) + toSumTree(node->right);
// Return the sum of values of nodes in left and right subtrees and
// old_value of this node
return node->data + old_val;
}
This has the complexity of O(n).
Explanation:
The correct statement about database services or database instances is
( B).<u>An instance of the cloud database operates as a service that handles all application requests to work with the data in any of the databases managed by that instance.</u>
<u />
Explanation:
An instance of the Database Engine can be defined as a service that <u>all application requests to work with the data in any of the databases managed by that instance.The data can be on the same system or can be on another system </u>
So in case of a Cloud based database engine
( B).<u>An instance of the cloud database operates as a service that handles all application requests to work with the data in any of the databases managed by that instance.</u>
