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. The WHERE clause filters out orders that have a non-null value for the shipDate column. The GROUP BY clause groups the results by customer ID, customer name, and order ID.

Windows has the most support out of the rest due to it being popular and widely accepted.

The largest positive integer number that may be expressed in 32 bits is indicated by the variable integer.MAX VALUE (i.e., 2147483647). This indicates that no integer number larger than 2147483647 is allowed in Java.

It can be difficult to remember such a precise and large number, but it is usually important in competitive programming to specify a variable's maximum or lowest value that a certain data type may carry.

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

Integer.MAX_VALUE

A constant named Integer.MAX VALUE in the Java.lang package's Integer class indicates that it stores the highest value that can be assigned to any integer variable. This actually equals

2^31-1 = 2147483647.

Each numeric type has a maximum and a lowest value that it can represent. Because there are only so many bytes that may be accessible, numbers are limited.

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)

SP = SP + 2

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.

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.
