The solution is the recursive Python 3 function below:
########################################################
def allNamePermutations(listOfNames):
# return all possible permutations of listOfNames
if len(listOfNames) == 0 or len(listOfNames) == 1:
# base case
return [listOfNames]
else:
# recursive step
result_list = [ ]
remaining_items = [ ]
for firstName in listOfNames:
remaining_items = [otherName for otherName in listOfNames if
(otherName != firstName)]
result_list += concat(firstName,
allNamePermutations(remaining_items))
return result_list
#######################################################
How does the above function work?
As with all recursive functions, this one also has a base case, and a recursive step. The base case tests to make sure the function terminates. Then, it directly returns a fixed value. It does not make a recursive call.
In the case of this function, the base case checked listOfNames to see if it was empty or only had one name. If any of the conditions were satisfied, a new list containing listOfNames is returned.
The recursive step is where the function allNamePermutations() calls itself recursively. The recursive step handles the case where listOfNames has more than one item. This step first iterates over each name in listOfNames, and then does the following;
Gets a name in listOfNameGets a list of other names in listOfNamesCalls allNamePermutations() on the list of other names to get a list of permutation of the other names.(By first getting the list of other names before passing it into
allNamePermutations(), we make sure the recursive step eventually
terminates. This is because we are passing a smaller list each time
we make the recursive call.)
Inserts the current name in front of each permutationAdds the results to the result list to be returned laterAfter the iteration, it returns the result list which will now contain all permutations of the names in the list.
The concat function is defined below
##################################################
def concat(name, listOfNameLists):
# insert name in front of every list in listOfNameLists
result_list = [ ]
for nameList in listOfNameLists:
nameList.insert(0, name)
result_list.append(nameList)
return result_list
#####################################################
If we run the sample test case below
####################################
name_list = ['Adam', 'Barbara', 'Celine']
allNamePermutations(name_list)
####################################
the following output is produced
[['Adam', 'Barbara', 'Celine'],
['Adam', 'Celine', 'Barbara'],
['Barbara', 'Adam', 'Celine'],
['Barbara', 'Celine', 'Adam'],
['Celine', 'Adam', 'Barbara'],
['Celine', 'Barbara', 'Adam']]

Create a procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information. The BB_BASKETSTATUS table lists events for each order so that a shopper can see the status, date, and comments as each stage of the order process is finished. The IDSTAGE column of the BB_BASKETSTATUS table identifies each stage; the value 3 in this column indicates that an order has been shipped. The procedure should allow adding a row with an IDSTAGE of 3, date shipped, tracking number and shipper. The BB_STATUS_SEQ sequence is used to provide a value for the primary key column. Test the procedure with the following information: o Basket # = 3 o Date shipped = 20-FEB-12 o Shipper = UPS o Tracking # = ZW2384YXK4957
Answer:
c
Explanation:
A procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information is in the explanation part below.
A representative from Brewbeans' shipping division can change an order's status and add shipment details by using the PL/SQL method STATUS_SHIP_SP, as shown in the following example:
CREATE OR REPLACE PROCEDURE STATUS_SHIP_SP (
p_basket_number IN NUMBER,
p_date_shipped IN DATE,
p_shipper IN VARCHAR2,
p_tracking_number IN VARCHAR2
)
IS
v_status_id NUMBER;
BEGIN
-- Get the next value from the BB_STATUS_SEQ sequence
SELECT BB_STATUS_SEQ.NEXTVAL INTO v_status_id FROM DUAL;
-- Insert a new row into the BB_BASKETSTATUS table
INSERT INTO BB_BASKETSTATUS (STATUSID, BASKETNO, IDSTAGE, STATUSDATE, COMMENTS)
VALUES (v_status_id, p_basket_number, 3, p_date_shipped, 'Shipped: ' || p_shipper || ', Tracking Number: ' || p_tracking_number);
-- Commit the transaction
COMMIT;
-- Display a success message
DBMS_OUTPUT.PUT_LINE('Order status updated. Shipment information added.');
EXCEPTION
WHEN OTHERS THEN
-- Display an error message
DBMS_OUTPUT.PUT_LINE('Error: Unable to update order status.');
-- Rollback the transaction
ROLLBACK;
END;
/
Thus, by doing this, the procedure will be called with the specified parameters, and if successful, a new entry with the proper shipping information for basket number 3 will be added to the BB_BASKETSTATUS database.

Just a quick question, how do you set something == to char and int in an if statement (java)
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
Your program must define the method:
public String checkCharacter(String word, int index)
this is what i got to but im stuck on how to find out if its a char or int
public class TollCalculation {
public double calcToll(int hour, boolean isMorning, boolean isWeekend) {
Scanner scnr = new Scanner(System.in);
int timeHour; // Time of travel hour (24 hour format)
int timeMinute; // Time of travel minute
int inputColon; // Used to read time format
String userInput; // User specified time
double tollAmount;
}
public static void main(String[] args) {
TollCalculation tollObj = new TollCalculation();
// Test the three samples from the specification.
System.out.println(tollObj.calcToll(7, true, false));
System.out.println(tollObj.calcToll(1, false, false));
System.out.println(tollObj.calcToll(3, true, true));
}
}
This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.

Write a function remove_duplicates that removes duplicates from an array. For example, if remove_duplicates is called with an array containing 1, 4, 9, 16, 9, 7, 4, 9, 11 … then the array is changed to 1, 16, 7, 4, 9. 11. Your function should have a reference parameter for the array size that is updated when removing the duplicates
The function is an illustration of loops
Loops are used to perform repetitive operations
The function in Java where comments are used to explain each line is as follows:
//This defines the remove_duplicates function
public static int remove_duplicates(int arr[], int n){
//If the length of the array is 0 or 1, then return the original array
if (n == 0 || n == 1) {
return n;
}
//This creates a new array
int[] newArr = new int[n];
//This initializes the index of the array to 0
int ind = 0;
//This iterates through the original array
for (int i = 0; i < n - 1; i++) {
//The following loop populates the new array with the unique elements of the original array
if (arr[i] != arr[i + 1]) {
newArr[ind++] = arr[i];
}
}
newArr[ind++] = arr[n - 1];
// The following loop changes the original array
for (int i = 0; i < ind; i++) {
arr[i] = newArr[i];
}
return ind;
}
At the end of the function, the duplicate elements of the array are removed

discuss the communicatin process giving detailed explanation on each process
Communications is fundamental to the existence and survival of humans as well as to an organization. It is a process of creating and sharing ideas, information, views, facts, feelings, etc. among the people to reach a common understanding. Communication is the key to the Directing function of management.
A manager may be highly qualified and skilled but if he does not possess good communication skills, all his ability becomes irrelevant. A manager must communicate his directions effectively to the subordinates to get the work done from them properly.
Communications ProcessCommunications is a continuous process which mainly involves three elements viz. sender, message, and receiver. The elements involved in the communication process are explained below in detail:
1. Sender
The sender or the communicator generates the message and conveys it to the receiver. He is the source and the one who starts the communication
2. Message
It is the idea, information, view, fact, feeling, etc. that is generated by the sender and is then intended to be communicated further.
Browse more Topics under Directing
Introduction, Meaning, Importance & Principles of DirectingElements of DirectionIncentivesLeadership3. Encoding
The message generated by the sender is encoded symbolically such as in the form of words, pictures, gestures, etc. before it is being conveyed.
4. Media
It is the manner in which the encoded message is transmitted. The message may be transmitted orally or in writing. The medium of communication includes telephone, internet, post, fax, e-mail, etc. The choice of medium is decided by the sender.
5. Decoding
It is the process of converting the symbols encoded by the sender. After decoding the message is received by the receiver.
6. Receiver
He is the person who is last in the chain and for whom the message was sent by the sender. Once the receiver receives the message and understands it in proper perspective and acts according to the message, only then the purpose of communication is successful.
7. Feedback
Once the receiver confirms to the sender that he has received the message and understood it, the process of communication is complete.
8. Noise
It refers to any obstruction that is caused by the sender, message or receiver during the process of communication. For example, bad telephone connection, faulty encoding, faulty decoding, inattentive receiver, poor understanding of message due to prejudice or inappropriate gestures, etc.

What is the difference between a computer’s RAM and its hard disk?
A. RAM is not volatile, which means that it is more reliable than a hard disk. A hard disk is volatile, which means that it is vulnerable to electronic interference.
B. RAM is volatile, which means that it does not retain information in memory after powering down. A hard is not volatile, which means that it retains information in memory after powering down.
C. RAM is not volatile, which means that it retains information in memory after powering down. A hard disk is also not volatile, which means that it retains information in memory after powering down.
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Answer:
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Explanation:
Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.
Answer:
Explanation:
RAM can be accessed faster than hard drive. – Any changes made to the file will be present in RAM while once the changes are saved it is copied to the hard drive permanently. – RAM needs power to store data, hard drives do not.
