Project Euler는 수학적인 문제들을 컴퓨터 프로그래밍으로 풀어가는 사이트로, 파이썬 연습과 알고리즘 문제 풀이 겸 이 사이트의 문제를 조금씩 풀어보려고 합니다.
Solution for the project Euler about programming problems.
It is not general solution, just a idea made by myself.
About project Euler
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
“Project Euler exists to encourage, challenge, and develop the skills and enjoyment of anyone with an interest in the fascinating world of mathematics.”
