Problem - 1289 好题.其实就是模拟IEEE754的格式,不过要注意的是,这里用的32位是float,用double就不对了. 代码如下: #include <cstdio> #include <cmath> #include <iostream> using namespace std; int main() { float x; while (cin >> x) { ; while (fabs(x) >= 2.0) x /= 2.0,…

题意: 给出一堆单词,如果有一个单词可以分成左右串两个单词,并且在所给的一堆单词中存在,就是hat词,统计所有这样的词,并按字典序输出. 思路: 注意定义,一个hat词可以被两部分已经存在的词组成,那么也可以是由两个相同的词组成,比如{abcabc,abc} 这样的abcabc也是满足条件的.解法,将所有的单词塞到一个哈希set中,遍历其中每个单词,对每个单词进行任意可能的拆解成两部分,在该set中找,如果两个部分都找到了,那么就成功.塞到另一个set中,最后将set中全部输出.…
