Projekt Euler – probem 4 in Ruby

Posted in Ruby

Let’s go on with part four of our mathematical soultions-series in Project Euler: Problem: The Largest palindrome product A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99. Find the largest palindrome made from the product of two 3-digit numbers. […]

Project Euler – problem 2 in Ruby

Posted in coffee break, Ruby

Hi folks, this is part two of our soultions-series for the mathematical problems in Project Euler. Project Euler – problem number two: “Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, […]

Project Euler – mathematical problem 1

Posted in coffee break, Ruby

I recently heared about “Project Euler” from a friend. For all of those who have not heared about this project: “Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve.” The first mathematical problem to solve was: If we list all the natural numbers below […]
