Hi HN,

I'd like to ask if there are any resources that would be handy to train one in algorithmic problem solving?

I've been practicing on Euler for a bit, but I'm getting to some of the harder questions where brute force just doesn't really cut it anymore and I hit a complexity ceiling.

I've intuitively (after reading some books) decided that I should approach these problems in 2 steps:

- attempt to divide the tests into smaller subsets - attempt to linearly reduce the number of tests within each subset

However this doesn't seem to be sufficient when dealing with more difficult problems. And there isn't a step-by-step guide to solving any type of problem... I look at some sample solutions for the problems and go "How on earth did they get that?!"

Yes, I will continue practicing, but any advice would be good as I'm going for an interview sometime soon. =)

Regards, Daryl
