Chapter 15, Problem 2FTE
Explanation of Solution
Given SQL statement:
SELECT * FROM Coffee WHERE ProdNum != ‘14-001’
Not-equal-to operator in SQL:
In SQL not-equal-to operator is “< >”.
- The “< >” operator tests whether one expression is not equal to another expression.
- If any one of the operands or both of the operands are NULL, result is NULL.
- It returns true if both of them have different values.
- It returns false, in case if both values are equal.
SELECT:
- The “SELECT” statement is been used for selecting data from a
database . - The result table is stored with data and is termed as result set.
- All the fields present in table could be selected using “SELECT” statement.
- The “FROM” denotes a clause to choose from a table.
- The “WHERE” clause specifies that SQL statement should only affect rows with specified criteria.
- The criteria are expressed in form of predicates.
- It is not a mandatory clause, but is used to limit number of rows affected by SQL statement...

2. Consider the following pseudocode for partition:
function partition (A,L,R)
pivotkey = A [R]
t = L
for i
L to R-1 inclusive:
if A[i] A[i]
t = t + 1
end if
end for
A [t] A[R]
return t
end function
Suppose we call partition (A,0,5) on A=[10,1,9,2,8,5]. Show the state of the list at the

Solving Sudoku using Grover's Algorithm
We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules:
•No column may contain the same value twice
•No row may contain the same value twice
If we assign each square in our sudoku to a variable like so:
1
V V₁
V3
V2
we want our circuit to output a solution to this sudoku.
Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the
conversion of classical decision problems into oracles for Grover's algorithm.
Turning the Problem into a Circuit
We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit

Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.

- In a network, information about how to reach other IP networks or hosts is stored in a device's routing table. Each entry in the routing table provides a specific path to a destination, enabling the router to forward data efficiently across the network. The routing table contains key parameters determining the available routes and how traffic is directed toward its destination. Briefly explain the main parameters that define a routing entry.arrow_forwardYou are troubleshooting a network issue where an employee's computer cannot connect to the corporate network.
