URAL 1658 思路: dp+记录路径 状态:dp[i][j]表示s1为i,s2为j的最小位数 初始状态:dp[0][0]=0 状态转移:dp[i][j]=min(dp[i-k][j-k*k]+1,dp[i][j])(0<=k<10) 在状态转移时用一个数组v[i][j]记录选的k 代码: #include<bits/stdc++.h> using namespace std; #define ll long long #define pb push_back #define…

题目链接 隔了一年零三个月,重新刷URAL,这题挺麻烦的输出路径.输出路径挺扯的,乱写了写乱改改就A了...我本来想用很靠谱,记录每一条路径的,然后输出最小的,结果Tle,然后我使劲水水又过了一组,发现别人的题解..直接来了一次 就过了..我乱搞了搞,倒着记录最小的,然后倒着输出,就过了... #include <cstring> #include <cstdio> #include <string> #include <iostream> #include…

Given Length and Sum of Digits... 题目链接: http://acm.hust.edu.cn/vjudge/contest/121332#problem/F Description You have a positive integer m and a non-negative integer s. Your task is to find the smallest and the largest of the numbers that have length m…

Sum of Digits / Digital Root In this kata, you must create a digital root function. A digital root is the recursive sum of all the digits in a number. Given n, take the sum of the digits of n. If that value has two digits, continue reducing in this w…

Description You are given a positive integer nn. Let S(x) be sum of digits in base 10 representation of xx, for example, S(123)=1+2+3=6, S(0)=0. Your task is to find two integers a,ba,b, such that 0≤a,b≤n, a+b=n and S(a)+S(b) is the largest possible…
