Python programming problem!

Suppose that there is a json file called data from the desktop. I want to print the value with the key of "year" and "country".

Json file below:

{

"A":{

"year":11,

"grade":A,

"country":America},

"B":{

"year":18,

"grade":C,

"country":England},

"C":{

"year":19,

"grade":B,

"country":China},}

I want a code that I can only replace the name of key from year to grade and the code could be work.

Write a program to remove extra blanks from text files. Your program should replace any string of two or more blanks with one single blank. It should work as follows:

* Create a temporary file.
* Copy from the input file to the temporary file, but do not copy extra blanks. * Copy the contents of the temporary file back into the original file.
* Remove the temporary file.

Your temporary file must have a different name than any existing file, so that no files other than the input file are changed. Your program should ask the user for the name of the file to be edited, but should not request a name for the temporary file. Instead, generate the name within the program. You can generate the temporary file using any strategy that is clear and efficient. For example, you could start with a name like TempX and check if that name already exists. If it doesn't, you can use that name for the temporary file; if it does exist, append additional random letters to the filename until you find a name that isn't already used.

Write a small C++ program with 4 functions (and main():

  • getNumbers()- what is the return, what are the parameters?
  • findMax()- what is the return, what are the parameters?
  • findMin()-what is the return, what are the parameters?
  • find()- should return the index of the element or a -1 indicating not found

The main function will call those methods and print the results of each.

1 // declare necessary variables
2 // declare array
3 double numbers[SIZE];
4 // Function prototypes
5
6 int main() {
7 // call getNumbers()with appropriate parameters passed
8    // print results of getNumbers()
9    // call and print results of findMax()
10    // call and print results of findMin()
11    // call and print results of find() when element is found
12    // call and print results of find() when element is not found
13 return 0;
14 }

  1. NOTE: output should be user friendly, eg, for find(), the code should not print a cryptic 3 or -1, the message should explain the results.
  2. No magic numbers.
  3. Use const array parameter where appropriate.

Problem Statement – Gymnastics Contest Java

The Adelaidean Gymnastics Federation is an organisation devoted to running the best Gymnastics contests in all of Adelaide.

In 2031, the School of Computer Science from the University of Adelaide was chosen to develop the Gymnastic Contest software. The competition has few criteria. The winner of the competition must demonstrate skills of good balance. Competitors must have the ability to jump high. A contestant should demonstrate coordination, strength and exhibit aesthetics during their routine. In this final project we require you to design all the features and functionalities for this event to happen.

We are focused on the final for this contest, when each finalist will be judged by the five skills aforementioned in a scale from 0.0 to 10.0. Besides, this the system also has to store competitors name, age and suburb and each finalist contains a moto, like “ I can bounce higher than anyone else!”

Requirements:

Design and develop the classes Contestant, Finalist and Contest.

● [30 % marks] Contestant: consist of a competitor;

● [30% marks] Finalist: consist of a Contestant Competitor that got into the finals in the gymnastics competition.

● [40 % marks] Contest : basic functionalities to guarantee that the contest will

happen; Specifications for the class Contestant:

Design and develop the classes Contestant, Finalist and Contest.

The class Contestant is a general class that represent any sort of competitor;

Requirements:

1. Implement the accessors and mutators;

2. Implement the parameters constructors;

a. Name, suburb, age;

b. Name, suburb, age and the skils: balance, jump, coordination, strength, aesthetics;

3. Implement function getMean(): this method aims to return the mean score of all skills from a Contestant;

Constraints:

1. Comment this code to acquire code style marks;

2. This problem represents 30% of your marks

a. Full marks: use abstraction, implement 1,2,3;

b. Half marks: implement at least 1,2;

c. No marks: doesn’t compile;

Specifications for the class Finalist:

/* * * * * * * *

class Finalist

This class inherit properties from the class Contestant.

This class aims to represent the Finalist of gymnastics contest for 2031

Requirements:

1. Implement the accessors and mutators;

a. moto;

2. Implement method display which displays each field of this contestant on a separate line with the name of the field then a “:” and then the value of the fields;

Constraints:

1. This problem represents 30% of your marks

a. Full marks: use inheritance, implement 1,2;

b. Half marks: implement at least 1,2;

c. No marks: doesn’t compile;

2. Observe that the property moto belongs to Finalist;

class Contest

This class depends on the data structure FinalistList containing items of the class Finalist.

This class aims to represent the Gymnastics Contest Final for the year 2031.

Requirements:

For the class Contest:

1. Implement method addFinalist;

2. Implement a method sortFinalist; that sorts by the mean of skills.

3. Implement the method printFinalists;

Constraints:

1. There are no restrictions regarding what resources use in order to implement this problem; it means that you can use either array, list, linked lists, etc...

2. There is a MAX NUMBER of 5 Finalists;

3. This problem represents 40% of your marks

a. Full marks: use linked list, and implement 1,2,3

b. Half marks: use array implement at least 2 out of 3;

c. No marks: doesn’t compile;

Details

addFinalist will take a Finalist as a parameter and add the finalist to the list if the number of finalist is beyond MAX_NUMBER an IndexOutOfBoundsException should be thrown.

sortFinalist will sort the FinalistList structure by the mean of the skills of the Finalists.

printFinalist will print the members of FinalistLists by calling display on each of the Finalist in

that list in the order they appear in that list.

In the C programming language, implement the translation from regular English to Euroglish. If the letters were uppercase, keep them uppercase in the replacement.

1. Remove one“e”from the end of words that are more than three characters long, if they happen to end in “e”.

2. Change all double letters to a single letter (including double spaces). Do not remove double line spacing (i.e. “\n”).

3. When a word ends in “ed”, change that to just “d”.
