思路:预处理

#include<bits/stdc++.h>
using namespace std;

int dp[11][1000001]={0};

int main()
{
    for(int i=2;i<=10;i++)
    {
        for(int j=1;j<=1000000;j++)
        {
            int t=j;
            int res=0;
            res=j%i;
            dp[i][j]=res+dp[i][j/i]+dp[i][j-1];
        }
    }
    int T;
    scanf("%d",&T);
    int n,b;
    for(int i=1;i<=T;i++)
    {
        scanf("%d%d",&n,&b);
        printf("Case #%d: %d\n",i,dp[b][n]);
    }
    return 0;
}

Digit sum-----The Preliminary Contest for ICPC Asia Shanghai 2019

A digit sum S_b(n)Sb?(n) is a sum of the base-bb digits of nn. Such as S_{10}(233) = 2 + 3 + 3 = 8S10?(233)=2+3+3=8, S_{2}(8)=1 + 0 + 0 = 1S2?(8)=1+0+0=1, S_{2}(7)=1 + 1 + 1 = 3S2?(7)=1+1+1=3. Given NN and bb, you need to calculate \sum_{n=1}^{N} S_b

题目:https://nanti.jisuanke.com/t/41412思路:dfs           先取ai>2  2^12>3000 因此至多取11个 其余用1补           (3000*2)-(3000+2)=2998 那么需要加入2998个1 正好3000位 所以 3000是ai最大取值           计算ans时 有重复元素的排列组合 :如1112233 res=7!/(3!*2!*2!)           另外预处理阶乘及其逆元 #include<bit
