Discription Create a code to determine the amount of integers, lying in the set [X; Y] and being a sum of exactly K different integer degrees of B. Example. Let X=15, Y=20, K=2, B=2. By this example 3 numbers are the sum of exactly two integer degree…

题目链接: (请自行百度进Ural然后查看题号为1057的那道题目囧~) 题目大意: Create a code to determine the amount of integers, lying in the set \([X;Y]\) and being a sum of exactly \(K\) different integer degrees of B. Example. Let \(X=15, Y=20, K=2, B=2\) . By this example 3 number…

题目大意 求给定区间[X,Y]中满足下列条件的整数个数:这个数恰好等于K个互不相等的B的整数次幂之和.例如,设X=15,Y=20,K=2,B=2,则有且仅有下列三个数满足题意: 输入:第一行包含两个整数X和Y.接下来两行包含整数K和B. 输出:只包含一个整数,表示满足条件的数的个数. 数据规模:1 ≤ X ≤ Y ≤ 2^31−1,1 ≤ K ≤ 20,  2 ≤ B ≤ 10. 题解 <浅谈数位类统计问题>的论问题~~~~~人生第一道数位DP,哈哈~~~O(∩_∩)O~~代码纯属抄袭~~~~…
