Euler problem # 206
I just solved my 78th problem from Project Euler. The solution was not complicated (just a little mathematical observation) and then brute force CPU.
I was working on Aya‘s new laptop, and I noticed the C# code took 9 seconds to run in “power saver” mode, and only 4 seconds in “high performance” mode. It turns out that Vista caps the CPU speed at 50% for power saver mode. Sweet.
(This might seem very obvious to some, however I haven’t operated a laptop for several years, and so this is new to me – if Windows XP does such tricks, it is far less explicit than Vista).
