Project Euler Problem 4: Extra

Couple of things to add to yesterday’s post about problem 4. As is so often the case in life, no sooner had I finished the article than I realised there was an obvious additional step I could make, which I’d somehow failed to spot. Regarding the C# solution, an easy win having implemented the Reverse extension [ READ MORE ]

Problem 4 is as follows: 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. Bit of an easy one, this. The approach is pretty simple to understand – first calculate [ READ MORE ]

This doesn’t just mean ‘get the unit test coverage up to scratch’, it also means we are working towards full end-to-end integration testing using, amongst other tools, some front-end automation tools such as QTP and Selenium.

The result is fascinating. It [ READ MORE ]
