hdu 2844 poj 1742 Coins 题目相同,但是时限不同,原本上面的多重背包我初始化为0,f[0] = 1;用位或进行优化,f[i]=1表示可以兑成i,0表示不能. 在poj上运行时间正好为时限3000ms....太慢了,hdu直接TLE(时限1s); 之 后发现其实并不是算法的问题,而是库函数的效率没有关注到.我是使用fill()按量初始化的,但是由于memset()可能是系统底层使用了四个字节拷 贝的函数(远比循环初始化快),效率要高得多..这就是为什么一直TLE的原因,fil…

看了这篇博客的讲解,挺不错的.http://www.cnblogs.com/goodness/archive/2010/05/04/1727141.html 判断无解的情况(写完七种境界才发现有直接判断无解的方法): 一个状态表示成一维的形式,求出除0之外所有数字的逆序数之和,也就是每个数字前面比它大的数字的个数的和,称为这个状态的逆序. 若两个状态的逆序奇偶性相同,则可相互到达,否则不可相互到达. POJ提交记录(从下往上依次为第1,2,3,4,5,6,7,8境界): HDU提交记录(从下往上…
