You are given two positive integers d and s. Find minimal positive integer n which is divisible by d and has sum of digits equal to s. Input The first line contains two positive integers d and s (1≤d
This way 题意: 给你一个不完整的数,知道它有n位,是m的倍数,总共q个询问,每次问你它第k大是多少。 题解: dp[i][j]表示到第i位的时候,模m为j时的个数。 我们用res表示当前枚举到的数模m是多少,然后枚举前面模m的余数, 那么状态转移方程就是 d p [ i ] [ ( r e s + k ) % m ] + = d p [ i − 1 ] [ k ] ; dp[i
A:能用3肯定用三,然后分类讨论即可 #include<bits/stdc++.h>using namespace std;const int N = 2e5+10,M=2*N,mod=998244353;#define int long longtypedef long long LL;typedef pair<int, int> PII;typedef unsigned long
