Whatever will I do? It’s summer, and I haven’t a thing to do. I feel like I’m lacking something. Probably because of the same reason I always feel lacking. I wanna do something. But there’s so much I could do, but I can’t spend my time doing them all. I wanna commit to one project, but how?
There’s so much that could be done, but how am I to decide? Openness is the greatest thing in the world, yet with it comes the greatest troubles.
What am I to do now? Well I’ve got a blog, might as well use it right? I should post on that everyday, try to get some traction on subscriber count.
…Right. I can do this.
…Just think of something.
Something.
Something.
这么说我是理解错题意了,不过原作者描述的不够清晰。。。如果短的字母里面有重复字符,应该也要在长串里面出现多次才行吧?所以Hash是必须的。不过Guy的问题谁能给点提示?- How can you optimize the manpipg of letters to primes?- Can you suggest a way to combine the prime representation with a bitmask to improve performance?还有出现多次的rack是啥意思?
