题意: 输入三个正整数N,K,P(N<=400,K<=N,2<=P<=7),降序输出由K个正整数的P次方和为N的等式,否则输出"Impossible". //找到最大可能的整数pos后从大到小爆搜,sample 1给的输出好像不是最大的序列.....…

该题还不错~. 题意:给定N.K.P,使得可以分解成N = n1^P + … nk^P的形式,如果可以,输出sum(ni)最大的划分,如果sum一样,输出序列较大的那个.否则输出Impossible. dfs枚举,为了防止超时,这里要预先将从1开始的i^p的值存储在factor数组中,直到i^p>n.然后dfs深度优先搜索,相当于把问题一步步分解,即若第一个因子是n1,则接下来我们要判断N-n1^p.k-1是否可行.同时存储当前因子的总和sum,要取sum最大的:还有上一次相加的因子的索引las…
