We managed to come up with a C++ code that shows us the stack at each individual step, based on data introduced from the keyboard.
In order to make things easier, we made a convention using binary numbers, so that "1" represents the coins with the black side facing up, and "0" the ones with the red side facing up.

Hello!
My name is Carlos, I’m 16 and I’m a student at “Emil Racovita” National College.
I am really excited to be a part if this project and I’m sure I will learn a lot of new and interesting things about some subjects I’m fascinated about.

My team and I (Maria) managed to find the rule by which we should turn the coins over so we'll obtain 0000..... or 1111.....
We are now trying to find a new rule by which to number how many moves we have to make. We think that we might obtain the answer by using the number of "changes" a stack has.
If the stack looks like 101001, it has four changes, after the first coin, the second one, the third one, and before the last one: 1 0 1 00 1.
That's all for now, I think that we could do with some help, if you got other ideas. <3

# data[].attributes.body
We successfully converted the C++ program into python, which is a language we are more familiar with in our school. We then wrote an other code to simule large numbers of positions and to gather data.

After listening to your solutions, we discovered that my team and I solved a different question than you. We considered that we are not allowed to flip only one coin at a time. We solved it being allowed to turn over at least two coins together. This is why our solution may look a bit more complex than yours! We promise that until next time we will write down both the solution for the common question and the solution for the modified problem, because we think that it would still be interesting to study this case too. We can't wait to talk to you again!

Hi everyone, I'm Ismaël from Lycée Val de Durance. I'm in 11th grade and I mostly study Mathematics and Physics. I'm interested in sciences, and I like trying and learning to understand how things around me work and where they come from or how they were created. I'm glad to be part of this project and I had the luck to be part of the Erasmus mobility, and meet some of you guys. Hope I'll have the occasion to meet everyone else during the year, it's always better to work together while seeing each other. I'm sure we're going to make a great work together, and that we'll enjoy this year exchanging about our topic. See ya !

Hi Im Gabriel, Im in 10th grade so 16 years old and im in the VDD highschool ( val de durance) with a bunch of people in here.
I was lucky enough to go to romania, so i got to work with differents schools, which is in my opinion the most intresting feature in this project apart from pure reaserch : work in groups and collaborate to resolve a compex subject
I hope to see everyone that hasnt been in romania. As izmael said, it's always better to work together while seeing each other.
Have a good one
See ya guys

Hi everyone! Our team (Clara, Rianna, Carlos) has made some progress since our video conference. We succeded in creating a C++ program which allows us to see every step of the algorithm, meaning it shows the stack after each switch, until it is left with only 1 sided coins. Moreover, we started writing our article.

# data[].attributes.body
Here is the program we made. First, you enter the number of coins, then the sequence formed of 1s and 0s.

hey guys! how’s everyone? :)
we just wanted to give you a little update and maybe some ideas.
We are almost done writing our article.
We also talked to Mr. Țurcaș and asked him how to proceed with the problem, so maybe calculating the average of moves in relation to the number of coins using other methods (except the (a+b)/2 formula) would (hopefully) give the same results and we can figure out some other stuff from there.
Do you have some other ideas?
If not, good luck! <3

We have just finished our article and now we are wondering what other questions we can try to answer, related to our problem, of course! If you have any suggestions feel free to tell us!
We thought that maybe we could try to find out if there are any other ways of making the stack have only one sided coins. We would also like to do something including probabilities,  but we are not sure what yet.
Hope you're doing great!

In the input we put the number of coins and then 1 to represent the black side of the coin and 0 for the white side. In the output we will see the initial stack made out of black circles for 1 and white circles for 0. We will also see the steps, the final stack and the total number of moves. Here is a printscreen.

Hello there! Welcome to the application Turning Over Coins. The goal of this app is to repeatedly turn one or more coins over, until all of the coins in the stack are facing with the black side up.

The app will show the most efficient and logical method of finding the solution, as well as the number of moves it requires.

Thank you! Have fun trying it!

Would you like to try the interactive version of the app or the animation?

The interactive version will let you choose the number of coins the game will start with, as well as the position of each coin (either facing with the black or white side up).

The animation will generate a random number of coins and their positions, then show the solution to the problem.

All the coins are with the black side up, so the problem is solved!

Total number of moves executed:
