Problem Description

Link to Project Euler problem 4

A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is \(9009=91\times99\).

Find the largest palindrome made from the product of two 3-digit numbers.

WARNING Solution ahead. Don't read more if you want to enjoy the benefits of Project Euler and you haven't already solved the problem.

Project Euler in Haskell #2

2012-04-10 — Article of 200 words Programming Haskell Project Euler

Problem Description

Link to Project Euler problem 2

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: 1,2,3,5,8,13,21,34,55,89, …

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
