RSS订阅原创 八皇后（还有待改进）
呃，实习开始了。由于当初选错方向的问题，无奈实习只能跟着中软（中软国际）学做网站项目。不太喜欢JAVA，但并不是说JAVA不好，前几天看的一个位操作，那个用JAVA的人写的代码也挺精湛的。不扯废话，上午没事，就想着写了个N皇后问题的代码。上午卡在了斜线的处理上，卡了两个小时。。。汗~！结果回去睡了个午觉，再调的时候没几分钟就弄好了。。。我个人感觉代码还有待改进，先把思路记录下。整体思路

原创 2.2-3 & 2.2-4
2.2-3n/2个；n个；O（n）解答：平均查找一般就能查出结果，前提是序列中有要查询的元素。最坏情况就是没有该元素出现在待查队列中，要进行全部扫描，所以查n次，O（n）为时间复杂度。2.2-4首先分析问题的要求，找出要解决问题的一个思路。然后寻找多个有效的解决问题方法，中啊出相对最好的方法，然后改进算法，在一定范围内缩小数据规模。
