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.....…
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.…
