Programming competitions are Mathematical problems that must be solved using programming. Some considerations are used to evaluate your solution. The time that your program needs to run and solve the problem. The amount of memory that the program needs to solve the problem. When you post the solution. The competitions always have determined time and a number of problems. You must solve the problems at that time.
These are some problems from programming competitions and solutions that I found. The solutions, for a while, are only in Python, soon I would like to solve the problems in C++.
Every problem has the question and solution. Sometimes the solution, which I found isn't the best, but how it's working I consider it. If you find a better solution to the problem and would like to share, or even challenge yourself be free to try and tell me how was your solution. Share knowledge in programming is always great.
Every solution posted will have some explanation. How is the problem, how the solution was implemented, and how the code works.
All the problems are from https://codeforces.com/. If you want to look for more challenges, feel free to find it in the site. If you have any doubt about it, question me, I will try to help you. Just considering I'm new in this programming competition, but I can help with I know.
