  Product of digits  For a given non-negative integer number N , find the minimal natural Q such that the product of all digits of Q is equal N . Input The first line of input contains one positive integer number, which is the number of data sets. Ea…

这道题目有人用DFS.有人用DP 我觉得还是最简单的贪心解决也是不错的选择. Ok,不废话了,这道题目的意思就是 原先存在一个严格递增的Arrary_A,然后Array_A[i] 的每位之和为Array_B[i] 现在给你一个Array_B, 让你在条件: Array_A[len] Minimize 下求出次数组 (当然我们很容易得出,如果Array_A[len] 不是最小化的,那么答案有无穷多,随意暴力一下都可以) 所以这题没有那么暴力= = 解题思路: 首先求出Array_B[i] 和 Ar…

题意:给你一个正整数\(n\),每次可以对\(n\)加一,问最少操作多少次是的\(n\)的所有位数之和不大于\(s\). 题解:\(n\)的某个位置上的数进位,意味这后面的位置都可以被更新为\(0\),所以我们从高位往低位记录一个\(sum\),然后根据情况判断即可. 代码: int t; int s; ll n; char str[N]; int main() { //ios::sync_with_stdio(false);cin.tie(0);cout.tie(0); t=read(); w…

The number 3797 has an interesting property. Being prime itself, it is possible to continuously remove digits from left to right, and remain prime at each stage: 3797, 797, 97, and 7. Similarly we can work from right to left: 3797, 379, 37, and 3. Fi…
