Task«Employee performance analysis system»

the company uses a system for evaluating employees according to various criteria. For each employee, his assessments are known for several parameters. It is necessary to create a function -generator that will return employees in decreasing their average assessment, but with memory optimization - processing data on one employee at a time.

Input format

The first line contains the number of N. The following are n lines, each contains the name of the employee and its assessment through the gap. The name consists of one word, assessment - integers from 1 to 10

Output format

the names of employees in the order of descending an average grade, each name on a new line. With the equality of average assessments, sorting by alphabet

Example

Input

3
Ivan 8 9 7
Maria 9 10 8
Peter 6 7 8

Output

Maria
Ivan
Peter

How to Solve Tasks?

1 - Read the task and understand what needs to be done

2 - The example shows how the input data will be provided and what output is expected

3 - Write the code considering the input, output, and the task itself.

(see example below)

Difference Between the "Run" and "Test on All Cases" Buttons

1 - The “Run” button executes your code only on one set of input data, and you’ll see the result in the output window.

2 - The “Test on All Cases” button runs your code against all test cases. If all tests pass, a banner will appear. If even one test fails, it will be highlighted in red.

(see example below)

How to Change Input Data

To change the input data, click the “Run Test” button next to the input data you want to execute.

Working with Input/Output Windows

1 - Input Data is the window containing the values loaded into your program in place of input()

2 - Program Output is the window showing what your program prints. If it’s green, the output matches the expected result; if red, there are differences.

3 - Expected Output is the reference value used to verify the solution.

(see example below)

Guide to the "Run Test" Button

1 - Green means the program produced the correct output

2 - Red means the program’s output didn’t match the expected output for this data. The program output and the expected output must be identical, including spaces and punctuation!

Criteria for a Correct Solution — How to Know It’s Right

If you see this banner, congratulations — everything is correct.

Topic Structure (30 Tasks: 10 Easy, 10 Medium, 10 Hard)

1 - The first 10 tasks are quite easy and contain hints covering only the essential parts of the topic.

2 - The next 10 tasks are medium difficulty. Their hints differ from the easy ones and reveal new aspects of the topic.

3 - The hardest tasks have no hints. Often, they include additional topics, so sometimes it’s better to move on and return later. Read the hints carefully — they offer new ways to solve already familiar problems.

(see example below)

Availability of Theory (Video + Text)

1 - Each block contains a “Theory” section.

2 - It always includes a detailed video.

3 - There is also a detailed guide with all the necessary theory and code examples.
