Code Kata: Project Euler #4, Finding Palindromes

Saturday, April 19th, 2008

This weekend, I solved problem 4 of Project Euler: 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. I designed a routine that checks whether ...

Code Kata: Project Euler #3 + CMake distributions

Sunday, April 13th, 2008

This weekend, I tackled the Project Euler problem #3: The prime factors of 13195 are 5, 7, 13 and 29. What is the largest prime factor of the number 600851475143 ? Pretty straightforward: Just test and recurse.

Code Kata: Project Euler #2 with CMake

Sunday, April 6th, 2008

Recently, I started to use the autotools for building a project. But I am really unhappy with it - although a lot of special cases can be handled by the toolchain, it is extremely complex to use and prone to user errors. Auto-Hell, I guess... So, this code kata is ...

Code Kata: Project Euler #1

Sunday, March 30th, 2008

Following the example of doing code katas, I spend my sunday morning thinking about integer performance in C++. Project Euler provides a nice collection of mathematical problems. As it turns out, some of my assumptions on C++ were totally wrong :-)
