摘要: 今天做了这两道题真的好高兴啊!!我一直知道自己很渣,又贪玩不像别人那样用功,又没有别人有天赋。所以感觉在ACM也没有学到什么东西,没有多少进步。但是今天的B题告诉我,进步虽然不明显,但是只要坚持努力的学习,改变就会默默发生啦~真的好高兴,感觉自己又有了动力!自己现在虽然还不会什么算法,都是三脚猫功夫,但是已经真切的感觉到自己已经会用一点算法的思想了,哎呀我也不知道怎么说好,总之就是看到了自己的改变。A -ArrayTime Limit:2000MSMemory Limit:262144KB64bit IO Format:%I64d & %I64uSubmitStatusPractice 阅读全文

摘要: 这是第一天的CF,是的,我拖到了现在。恩忽视掉这个细节,其实这一篇只有一道题,因为这次一共做了3道题,只对了一道就是这一道,还有一道理解了的就是第一篇博客丑数那道,还有一道因为英语实在太拙计理解错了题意,然后就没看了,现在更不想看了。再次感觉自己做题就是靠脑子,找规律。不像其他大牛一样一说解题思路,就是一套一套的算法。啊有时候听到头都晕了。。。好了言归正传吧。D -DTime Limit:1000MSMemory Limit:65536KB64bit IO Format:%I64d & %I64uSubmitStatusPracticeURAL 1010DescriptionThere 阅读全文
