New Coding Score

We are also excited to announce the CodeSignal Coding Score! Under your new dedicated “My Profile” tab, you’ll find a new section called “Coding Score”. This score is an overall measurement of your implementation and problem-solving abilities and a predictor of how you will perform in technical interviews. Whether you’re measuring your own skills as you learn new ones, comparing your skills to those of your friends, or finding a new job; the CodeSignal Coding Score will be your way of showing your skills to the world.

Problem: app.codesignal.com/arcade/db/always-leave-table-in-order/jxvpRwWSTtmQne5XN

At the end of every semester your professor for "Introduction to Databases" saves the exam results of every student in a simple database system. In the database table Grades, there are five columns:

Name: the name of the student;
ID: the student's ID number (a 5 byte positive integer);
Midterm1: the result of the first midterm out of 100 points;
Midterm2: the result of the second midterm out of 100 points;
Final: the result of the final exam, this time out of a possible 200 points.
According to school policy, there are three possible ways to evaluate a grade:

Option 1:
Midterm 1: 25% of the grade
Midterm 2: 25% of the grade
Final exam: 50% of the grade
Option 2:
Midterm 1: 50% of the grade
Midterm 2: 50% of the grade
Option 3:
Final exam: 100% of the grade.
Each student's final grade comes from the option that works the best for that student.

As a Teaching Assistant (TA), you need to query the name and id of all the students whose best grade comes from Option 3, sorted based on the first 3 characters of their name. If the first 3 characters of two names are the same, then the student with the lower ID value comes first.

Elections are in progress!

Given an array of the numbers of votes given to each of the candidates so far, and an integer k equal to the number of voters who haven't cast their vote yet, find the number of candidates who still have a chance to win the election.

The winner of the election must secure strictly more votes than any other candidate. If two or more candidates receive the same (maximum) number of votes, assume there is no winner at all.

Below we will define an n-interesting polygon. Your task is to find the area of a polygon for a given n.

A 1-interesting polygon is just a square with a side of length 1. An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. You can see the 1-, 2-, 3- and 4-interesting polygons in the picture below.

Ticket numbers usually consist of an even number of digits. A ticket number is considered lucky if the sum of the first half of the digits is equal to the sum of the second half.

Given a ticket number n, determine if it's lucky or not.
