Answer:
Customer(1) - (1) Vehicle.
Explanation:
Cardinality is the mapping of entities or group of entities to a cardinal value. It tries to show the relationship between two objects like a cups in a shelf or plates in racks.
The car dealer in the question, sells one car to a customer and keep or prioritise the record of the main owner of the acquired vehicle. So the maximum cardinality assignment of the customer and vehicle is one (1) to one (1) mapping.
Answer:
There are two customers in the PostalCode.
SQL statement for select all the fields and the rows from the Customers table where PostalCode is 44000.
SELECT * FROM Customers WHERE PostalCode = "44000";
Explanation:
The SELECT statement retrieve zero or more than one row from 1 or more than one the database tables or the database views.
In most of the applications, the SELECT query is most commonly used for DQL(Data Query Language) command.
SQL is the declarative programming language and the SELECT statement specifies the result set, but they do not specifies how to calculate it.
Math.random() is a built-in function in JavaScript that generates a random number between 0 and 1.
<h3>What is Math.random()?</h3>
Math.random() is a useful and versatile function that can add a element of randomness to your JavaScript programs.
This function can be used in a variety of ways in JavaScript programs, such as:
- Generating random numbers for games or simulations.
- Creating random samples for statistical analysis.
- Shuffling elements in an array for a random order.
- Selecting random items from a list for a quiz or survey.
- Creating unique IDs or keys for objects in a database.

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:
Answer: If a customer orders more than four pizzas, the program should deduct 10% from the cost of the order. Modify the program appropriately, and then save, run, and test it.
