(BruteForce)暴力破解经典题目总结

在算法竞赛中,很多问题是来不及用数学公式推导出来的.或者说根本就找不到数学规律,这时我们就需要使用枚举来暴力破解. 不过枚举也是需要脑子的,一味的暴力只能超时.因此我这里选择了几道mooc上经典的题目来做复习. 1.完美立方. 思路: 从2到N枚举a的值,2到a枚举d的值,2到d的枚举b的值,2到c枚举b的值.当满足a*a*a==b*b*b+c*c*c+d*d*d 的时候对结果输出. 代码如下: #include <iostream> using namespace std; int mai…

POJ题目排序的Java程序

POJ 排序的思想就是根据选取范围的题目的totalSubmittedNumber和totalAcceptedNumber计算一个avgAcceptRate. 每一道题都有一个value,value = acceptedNumber / avgAcceptRate + submittedNumber. 这里用到avgAcceptedRate的原因是考虑到通过的数量站的权重可能比提交的数量占更大的权重,所以给acceptedNumber乘上了一个因子. 当然计算value还有别的方法,比如POJ上…
