Create a recursive procedure named (accumulator oddsum next). The procedure will return the sum of the odd numbers entered from the keyboard. The procedure will read a sequence of numbers from the keyboard, where parameter oddsum will keep track of the sum from the odd numbers entered so far and parameter next will (read) the next number from the keyboard.
Answer:
Explanation:
The following procedure is written in Python. It takes the next argument, checks if it is an odd number and if so it adds it to oddsum. Then it asks the user for a new number from the keyboard and calls the accumulator procedure/function again using that number. If any even number is passed the function terminates and returns the value of oddsum.
def accumulator(next, oddsum = 0):
if (next % 2) != 0:
oddsum += next
newNext = int(input("Enter new number: "))
return accumulator(newNext, oddsum)
else:
return oddsum

A ___________ is a variable used to pass information to a method.
Answer:
A parameter is a variable used to pass information to a method.
Explanation:
A parameter is a variable used to pass information to a method.
What are the features of parameter?In general, a parameter "beside, subsidiary" is any quality that aids in describing or categorizing a certain system. In other words, a parameter is a component of a system that is crucial or useful for identifying the system or assessing its functionality, status, or other characteristics.
In some fields, such as mathematics, computer programming, engineering, statistics, logic, linguistics, and electronic music production, the term "parameter" has more precise definitions.
In addition to its technical applications, it also has broader meanings, particularly in non-scientific situations. For example, the terms "test parameters" and "game play parameters" refer to defining qualities or boundaries.
A novel method of characterizing surface texture, in particular surfaces having deterministic patterns and features, is the use of feature parameters.
Traditional methods for characterizing surface texture, such profile and areal field parameters, are considered as supplementary to the feature parameter approach.

SOMEONE PLS HELP?!?!!
Answer:
B. To continuously check the state of a condition.
Explanation:
The purpose of an infinite loop with an "if" statement is to constantly check if that condition is true or false. Once it meets the conditions of the "if" statement, the "if" statement will execute whatever code is inside of it.
Example:
//This pseudocode will print "i is even!" every time i is an even number
int i = 0;
while (1 != 0) //always evaluates to true, meaning it loops forever
i = i + 1; // i gets incrementally bigger with each loop
if ( i % 2 == 0) //if i is even....
say ("i is even!"); //print this statement

Which of the following transfer rates is the FASTEST?
1,282 Kbps
O 1,480 Mbps
1.24 Gbps
181 Mbps
Answer:
The correct answer is 1,480 Mbps.
Explanation:
For this you have to know how to convert bytes to different units.
1,000 Bytes (b) = 1 Kilobyte (Kb)
1,000 Kilobyte (Kb) = 1 Megabyte (Mb)
1,000 Megabytes (Mb) = 1 Gigabyte (Gb)
and Finally, 1,000 Gigabytes (Gb) = 1 Terrabyte (Tb)
Answer:
1,480 Mbps
Explanation:
1,480 Mbps is equal to 1.48 Gbps, and so it is the fastest transfer rate listed because it is greater than 1.24 Gbps. In summary, 1,480 Mbps > 1.24 Gbps > 181 Mbps > 1,282 Kbps.

For this question we won't be directly working within LinkedList however. Instead, we'll be working with a Runner class:
public class Runner {
private LinkedList firstItemList;
private LinkedList listRemainder;
public Runner() {
firstItemList = null;
listRemainder = null;
}
}
For this question, write a method for the Runner class that will take in a LinkedList, split into two linked lists, and assign their values to firstItemList and listRemainder. Assign firstItemList to be a new LinkedList that just contains the first value. Assign listRemainder to be a new linkedList that contains everything EXCEPT the remainder.
More clearly, if you are given a linked list that looks like: 1 --> 2 --> 3 --> 4 Then assign firstItemList to 1 --> null and listRemainder to `2 --> 3 --> 4``
Please note this will be the only question that deals with a Runner Class instead of the LinkedList class directly.
public void split(LinkedList wholeList) {
}// end split
Solve in JAVA please using LinkedList methods and Node methods only if necessary
Answer:
Explanation:
The following method will take in a LinkedList as an argument and split it, adding only the first element to the firstItemList and the rest of the elements to listRemainder. The firstItemList and ListRemainder may have to be changed to static in order for the method to be able to access them, or add a setter/getter method for them.
public static void split(LinkedList list) {
firstItemList = new LinkedList();
listRemainder = new LinkedList();
firstItemList.add(list.peek());
list.pop();
listRemainder = list;
}
The complete java code for the Runner class can be defined as follows:
Java Code:public class Runner<T>//defining a class Runner
{
private LinkedList<T> firstItemList;//defining LinkedList type array variable that is firstItemList
private LinkedList<T> ListRemainder;//defining LinkedList type array variable that is ListRemainder
public Runner()//defining default constructor
{
firstItemList=null;//holding null value in list type variable
ListRemainder=null;//holding null value in list type variable
}
public void split(LinkedList<T> WholeLinkedList)//defining a method split that takes a list in parameter
{
if(WholeLinkedList==null)//defining if block that checks parameter variable value equal to null
return;//using return keyword
firstItemList=WholeLinkedList;//holding parameter variable value in firstItemList
ListRemainder=WholeLinkedList.next;//holding parameter variable next value in ListRemainder
firstItemList.next=null;//holding null value in firstItemList.next element
}
}
Code Explanation:
Defining a class Runner.Inside the class two LinkedList type array variable that is "firstItemList, ListRemainder" is declared.In the next step, a default constructor is defined, in which the above variable is used that holds null value in list type variable.In the next line, a method "split" is declared in which it accepts "WholeLinkedList" as a parameter.Inside this, if a conditional block is defined that checks parameter variable value equal to null if it's true it returns nothing.outside the conditional block, it checks the parameter value and holds value in it.Find out more about the linked list here:

Write a recursive method called permut that accepts two integers n and r as parameters and returns the number of unique permutations of r items from a group of n items. For given values of n and r, this value P(n, r) can be computed as follows:
n!/(n - r)!
For example , permut (7, 4) should return 840.
Answer:
Following are the code to the given question:
public class Main//defining a class Main
{
static int permut(int n, int r)//defining a method permut that holds two variable
{
return fact(n)/fact(n-r);//use return keyword to return calcuate value
}
static int fact(int n)//defining a fact method as recursive to calculate factorials
{
return n==0?1:n*fact(n-1);//calling the method recursively
}
public static void main(String[] abs)//main function
{
//int n=7,r=4;//defining integer variable
System.out.println(permut(7,4));//use print method to call permut method and print its values
