http://wikioi.com/problem/1017/ 划分型动态规划1.转移方程是:f[i][j]=max(f[k][j-1]*t[k+1][i]),f[i][j]表示前面i个字符加上j个乘号所得的最大值,t[i][j]表示i到j的数值:2.可预处理,先计算出每段的数字值:3.看代码分析错误实在不行时,还是debug一下吧. #include <cstring> #include <iostream> #define ulong long long using names…
Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 这个求最大子数组乘积问题是由最大子数组之和问题演变而来,但是却比求最大子数组之和要复…
