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. This one was tough. I ended up calculating every palindrome for every 3 digit number, saving it intoContinue reading “Largest Palindrome Product of 3 Digit Numbers”

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 theContinue reading “Even Fibonacci Sums”

I’ve been doing the projecteuler.net coding puzzles. I’m going to blog about my design decisions (I won’t post any actual code nor results, just pseudo code). #1: Multiples of 3 and 5 If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9.Continue reading “Project Euler Programming Puzzles!”
