c++ program to calculate the sum of the rows and the columns in a multidimensional array

Write a program that reads a student's code and grades from all four tests
of any matter; and calculate and print the final grade for the subject, along with the
student code. Taking into account that:
The value of the first  is 15%
The value of the second  is 25%
The value of the third  is 30%
The value of the fourth  is 40%

You has been requested to design and develop a food ordering system in C++ language based on following requirements:

The system shall allow the user to place an order for the food(s), view the food details, modify or delete the details of the food if necessary. Your program should be menu driven, giving the user various choices. You shall design the system by demonstrating the full understanding of object-oriented and use of list/link-list concept.

For every food order, the following information will be stored: Order ID (Auto assigned, unique ID), Food Code, flavor (example: Strawberry, chocolate), weight (Kg), Unit Price, Qty and customer information who order this cake. The customer information consists of customer ID, name, address and contact number. The order ID shall be automatically assigned with a unique ID when new order is added. The system shall display additional information that is amount (unit price * qty) when viewing the order details.

Write a method to return the surface area of a right rectangular prism given the dimensions Example: surface_area(3, 5, 7) returns 142. Java Program (Using Method)

Write a Python function that will ask the user for an integer X bigger than 20 and return a list "ls" of 10 distinct random integers taken between the interval 0, to X. None of the 10 elements of "ls" should be repeated.

Show algebraically the payoff of a butterfly spread using calls in the following cases:

– ST < K1
– K1 < ST < K2
– K2 < ST < K3
– ST > K3

Assume K2 is the average of K1 and K3: K2 = .5*(K1 + K3) or 2K2 = K1 + K3 (i.e., the butterfly trade is symmetric). You can use this relationship to simplify the final expressions quite a bit.

Write a Python function that will return the index of an element in a list.1- The function will receive a list of at least 5 numbers as a single argument when the function is called. 2. The function will ask the user to input a number and will find and return the index of that number in the list.3. If the number is not an element of the list, the function returns the string "unknown."

1. Yes or No? Recall the heuristics from the 8-puzzle problem: h1 is the number of out of place tiles, and h2 is the Manhattan distance. Is a combined heuristic (h1 + h2)/2 also admissible? Provide a justification.

2. In a fully observable, turn-taking, zero-sum game between two perfectly rational players, it does not help the first player to know what move the second player will make.

Write a Python program that will ask the user to input a word, will return the first letter of the input word, and ask the user to put another word, and so on, in the form of a loop. If the user chooses to stop, he or she should input the integer "0" for the loop to stop.

1. The minimax algorithm yields sub-optimal utilities against sub-optimal opponents.Yes or No? Provide a justification.

2. Alpha-beta pruning allows minimax to search deeper into the game tree by obtaining a more accurate estimate of the evaluation function, i.e. by calculating better bounds. Yes or No? Provide a justification.

Write a Python function that will do the following:1. Ask the user to input an integer which will be appended to a list that was originally empty. This will be done 5 times, meaning that when the input is complete, the list will have five elements (all integers).2. Determine whether each element is an even number or an odd number3. Return a list of five-string elements "odd" and "even" that map the indexes of the elements of the input list, according to whether these elements are even or odd numbers. For example: if the input sequence is 10, 7, 9, 51, and 100, the function will return the list ["even", "odd", "odd", "odd", "even"].

In this programming question, n integers ranging from 0 to n-1 are stored randomly in A, an array of size n. In the class Sort.java, you are supposed to implement the following two sorting algorithms: Insertion-sort and Heap-sort. You have to work directly on the given starter code.

• Download the starter code from the course web site. Read the starter code and make sure you understand how it works before attempting to modify it. In the given class Sort.java, Selection-sort is already implemented and is used to sort an array of numbers from 0 to 9.

  Initially, the array is: 0123456789

  After randomization, the array becomes: 8201954367

       SELECTION SORT...
  

  The array is now sorted: 0123456789

• Implement Insertion-sort and Heap-sort in the Sort class.

• ////////

• import java.util.Random;

  public class Sort {
        
     // swap the ith element with the jth elements.
     private void swap(int[] a, int i, int j){

         temp = a[i]; a[i] = a[j]; a[j] = temp;
     }
    
     // initialize the array a with elements from 0 to size-1.
     public void initializeArray(int[] a, int size){

         int rowSize=100;
         for (int i=0; i            if(i%rowSize==0){

             }
             System.out.print(a[i]+ " ");
         }
         System.out.println();
     }
    
     // randomly swap two elements in a for SWAPTIMES times.
     public void randomizeArray(int[] a, int size){

         Random r = new Random();

     j = r.nextInt(size);
     k = r.nextInt(size);
