摘要：题目："The problem is, given an positive integer N, we define an equation like this:N=a[1]+a[2]+a[3]+...+a[m];a[i]>0,1m时，f(n,m)=f(n,m-1)+f(n-m,m)。//难点，也是整个递归法的重点 此时还可分为两种情况讨论：a.当划分中不包含m时：因不包含m，故剩下的划分数都比m要小，其中最大的为m-1,因此，这种情况下的划分个数为f(n,m-1)；b.当划分数包含m时：即{m,(a1,a2,a3，...,ai)},其中（a1,a2,a3,...,ai）的和为 阅读全文
