题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805364711604224 题意: 给定一个数n,要求从1~n中找出k个数,使得这些数的p次方之和等于n 思路: 因为n为400,所以dfs加剪枝[本来还在想dp来着] 他要求输出的方案是数字之和最大的,如果之和相等要输出字典序较大的. 所以还需维护一个数字之和. 一个剪枝的方法是从大到小进行dfs,后面被选的数一定比前面被选的要小,这里不限制的话显然会出现重复.…

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…
