to be written in c++ only

Objectives
 To be able to solve problem using branch an bound strategy
 To be able to find the minimized cost
 To practice writing solutions to problems in a clear and succinct way
Problem
Let there be N workers and N jobs. Any worker can be assigned to perform any job, incurring
some cost that may vary depending on the work-job assignment. It is required to perform all jobs
by assigning exactly one worker to each job and exactly one job to each agent in such a way that
the total cost of the assignment is minimized. Write a program using branch and bound strategy to
show who will be assigned which job and the total cost incurred.

: In the context of state diagrams in system design, describe what is an event, state, transition and conditions?

Describe an algorithm that could be used to solve the Tee Puzzle. In this puzzle, the board consists of a 5 sided triangle full of golf tees. One hole is empty. You can jump a tee over an adjacent tee as long as it lands into an empty hole. The jumped tee is removed. The goal is to have one tee remaining.

Add a function to Programming Challenge 7 that allows the user to search the structure array for a particular customer's account. It should accept part of the customer's name as an argument and then search for an account with a name that matches it. All accounts that match should be displayed. If no account matches, a message saying so should be displayed. Currently I have

#include <string>

1. Practice Tasks

Aims: to simulate the principles and key technology in operating systems. You need to analyze, design, implement and debug a program which simulates the chosen principles or technology. You need to finish the following tasks to do the practice:

1) CPU scheduling algorithms (including FCFS, SJF, Priority Scheduling, Round Robin)

2) Process Synchronization (including producer and consumer problem, reader and writer problem, Dining-Philosophers Problem)

3) Page replacement algorithm (including FIFO, LRU, Optimal Algorithm)

4) Disk scheduling algorithm (including FCFS, SSTF, SCAN)

You need to implement the above 4 tasks to do the practice. You need to implement the input, algorithms and the output. The output will be different when you switch to different algorithms.

2. Requirements

1) Requirement analysis

2) Function design

3) Code preferebly in c/c++ or java

4) Report write-up

Python problem

I don't know how to arrive to the answer of this question:

"Rounded to the nearest integer, how much higher is the average sum of all six stats among Mega Pokemon than their non-Mega versions? Note that Mega Pokemon share the same Number (the first column) as their non-Mega versions, which will allow you to find all Pokemon that have a Mega version."

For this problem below. The format of the file is included at the bottom but it's not complete. If you want the complete one, let me know and I can email it to you.

#The line below will open a file containing information
#about every pokemon through Generation 7:

pokedex = open('../resource/lib/public/pokedex.csv', 'r')

#We've also provided a sample subset of the data in
#sample.csv.
#
#Each line of the file has 13 values, separated by commas.
#They are:
#
#
# - Number: The numbered ID of the Pokemon, an integer
# - Name: The name of the Pokemon, a string
# - Type1: The Pokemon's primary type, a string
# - Type2: The Pokemon's secondary type, a string (this
# may be blank)
# - HP: The Pokemon's HP statistic, an integer in the range
# 1 to 255
# - Attack: The Pokemon's Attack statistic, an integer in
# the range 1 to 255
# - Defense: The Pokemon's Defense statistic, an integer in
# the range 1 to 255
# - SpecialAtk: The Pokemon's Special Attack statistic, an
# integer in the range 1 to 255
# - SpecialDef: The Pokemon's Special Defense statistic, an
# integer in the range 1 to 255
# - Speed: The Pokemon's Speed statistic, an integer in the
# range 1 to 255
# - Generation: What generation the Pokemon debuted in, an
# integer in the range 1 to 7
# - Legendary: Whether the Pokemon is considered "legendary"
# or not, either TRUE or FALSE
# - Mega: Whether the Pokemon is "Mega" or not, either TRUE
# or FALSE

#Here, add any code you want to allow you to answer the
#questions asked below over on edX. This is just a sandbox

PartA: Create the database. Name the database doctorWho. Then create a page that allows Doctor Who’s assistant to add a new patient record. You will need to give the assistant rights to this database. The assistant’s username is 'helper' and the password is 'feelBetter'. For this to work, you will need to create several pages so be sure to include all of them when submitting your work. Name the main page addPatient.php.

PartB: Add at least five records to the patient's table in the doctorWho database you created in PartA. Now create a page that will display three or more fields from each of these records. The display should consist of, at a minimum, the patient’s first and last names, and a unique identifier. Name the page getPatient.php and be sure to include the necessary accompanying files when you submit your work.

int main(){
   int i = 3;

   if(fork()){
   i++;
   fork();
   i+=3;
   }else{
   i+=4;
   fork();
   i+=5;
   }
   printf("%d\n",i);
}

Course name object oriented programming.

3) Define the following methods:

- constructors: create two constructors with and without parameters.

- setName: this method sets the name of the School.

- getName: this method returns the name.
