What are one-line solutions?
Solving an problem from project euler can be a challenge or coding fun. The result of every problem is only one number, calculated by an algorithm. Some algorithms can be written as one expression. You get an one-liner if you can embed it in a function with only one line of code.
What is 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.
After solving some project euler problems with python I got some one-line solutions with nice usage of list comprehensions and functional programming. These code examples are not clean code but a challenge to find more one-line solutions. This article include my first 10 solutions for project euler as one-line python function. Dont use it to cheating the project - it should be a motivation to find smart coding solutions and participate to project euler. Read more
