The security principle that Tomahawk Industries is following is "Separation of duties". This principle is designed to prevent any single individual from having complete control over a critical system or process.

This principle is designed to prevent any single individual from having complete control over a critical system or process. In the case of Tomahawk's weapon control system, requiring two different officers to enter their access codes ensures that no single person has complete control over the system's use. By dividing the duties of access control between two individuals, the risk of unauthorized use or misuse of the system is reduced. This principle is commonly used in industries where safety and security are of utmost importance, such as military, finance, and healthcare.

The correct answer is C) "abcd" and "dcba".

The given hash function calculates the hash value of a string s by iterating through each character in the string and adding up the product of the position of the character in the string and the ASCII code of the character plus one. The ASCII code of 'a' is 97, so s[i]-'a'+1 gives the value of the character as an integer starting from 1.

With this information, we can determine which of the following pairs will have the same hash value:

A) "abc" and "bcd" will not have the same hash value because the order of the characters matters in the calculation of the hash value.

B) "abc" and "cba" will not have the same hash value because the order of the characters matters in the calculation of the hash value.

C) "abcd" and "dcba" will have the same hash value because even though the order of the characters is different, the product of each character's position and its ASCII code plus one will be the same for both strings.

Therefore, the correct answer is C) "abcd" and "dcba".

To create the giveaway.java file, you would first need to define a giveaway class that contains a main method.

The main method would implement the logic for allowing people to take items from the initial array of available items. The initial array could be represented as a 5x5 grid, with each element representing an item available for grabs. You would need to prompt the user for input to select which item they want to take, and then update the array to reflect the item that has been taken. To make the program user-friendly, you could display the array to the user with each element labeled with a unique identifier. You could also add handling to handle cases where the user provides an invalid input, such as selecting an item that has already been taken.

The error in the first query is joining the Order_ table without a join condition, and the error in the second query is using = Null to filter for null values instead of using IS NULL.

1. To select each customer, find how many orders each customer makes, and average the order amount for each customer, you can use the following SQL query:

SELECT c.custName, COUNT(o.orderID) AS No_of_orders, AVG(i.orderAmount) AS avg_order_amt

FROM Customer c

JOIN Orders o ON c.customerID = o.customerID

JOIN OrderItems i ON o.orderID = i.orderID

GROUP BY c.custName;

This query joins the Customer, Orders, and OrderItems tables and uses the COUNT and AVG aggregate functions to calculate the total number of orders and the average order amount for each customer. The GROUP BY clause groups the results by customer name.

2. To find the customerID, customer name, orderID, and total value of the order for those orders that have not been shipped, you can use the following SQL query:

SELECT c.customerID, c.cname, o.orderID, SUM(i.price * i.quantity) AS total_value

FROM Customer c

JOIN Orders o ON c.customerID = o.customerID

JOIN OrderItems i ON o.orderID = i.orderID

WHERE o.shipDate IS NULL

GROUP BY c.customerID, c.cname, o.orderID;

This query joins the Customer, Orders, and OrderItems tables and uses the SUM aggregate function to calculate the total value of each order.

Maximum string length is 50 characters. int freq[26] = 0; / Initialize frequency array to zero. int i, j, count = 0. char unique[26]; int main() char str[51];

Java consequently offers constants to represent these integers, allowing for easy assignment of the values to variables without having to enter the complete value.

A SQL SELECT statement's ORDER BY clause comes last. Following a series of expressions (ASC | DESC) on which the data should be sorted are the keywords ORDER BY (Ascending Order or Descending Order).

Although they frequently are columns, these phrases are not required to be columns. Additionally, they could be computations or column ordinals. It's permissible to combine many expression types in the same ORDER BY clause. Additionally, the expressions are not required to appear in the query's output.

A singleton can be used with an ORDER BY clause, but any number of expressions can be used. A comma is used to separate each phrase in an ORDER BY clause when there are numerous ones.

Each expression has its own separate setting for the sort direction. The extra keywords ASC or DESC after each expression will instruct SQL Server to sort that expression in either ascending or descending order, as appropriate. The expression will be sorted ascending by default if neither the ASC nor the DESC keyword is present. This makes instances of the ASC keyword in use incredibly uncommon.

If the device has 2KB of RAM, then the maximum stack size would be 2KB.

In programming, a stack is a data structure that stores a collection of elements and operates on a last-in, first-out (LIFO) basis. The stack data structure consists of two primary operations: push and pop. The push operation adds an element to the top of the stack, while the pop operation removes and returns the top element of the stack. Stacks are often used in programming for tasks such as tracking function calls, managing memory allocation, and parsing expressions.

Here,

Using RTL notation, the operations carried out to execute the "push r9" and "pop r9" instructions are as follows:

push r9: The current value of the stack pointer (SP) is loaded into a temporary register (e.g. R10). The value of the register r9 is then written to the memory location pointed to by SP, and the stack pointer is decremented by 2 (assuming a 16-bit architecture).

R10 = SP

*(SP) = r9

SP = SP - 2

pop r9: The value at the memory location pointed to by SP is loaded into register r9, and the stack pointer is incremented by 2.

r9 = *(SP)
