若无解或者答案超过100位,输出no solution。 n最大=900,m最大=8100 dp[i][j]表示和为i,平方和为j的最少位数 dp2[i][j]表示和为i,平方和为j的最小首位数 竟然一直在思考有前导0怎么办,最优解肯定不能出现0啊啊啊 #include<cstdio> #include<algorithm> using namespace std; #define N 901 #defi...
Input The first line contains the number of test cases t (no more than 10000). In each of the following t lines there are numbers s1 and s2 (1 ≤ s1, s2 ≤ 10000) separated by a space. They are the sum of digits and the sum of squared digits of the number n. Output For each...

I want to understand that you can break a problem down, select a good algorithm, turn this into functioning (tested) code, understand the time and space complexity of your solution, appreciate any limitations, and understand possible optimizations. If you fell into the ‘trap’ above, it ...
Maximum Sum of Digits(CodeForces 1060B) 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)...

CodeForces - 1373E Sum of Digits(贪心) 技术标签: CodeForces上分 贪心题目链接:点击查看 题目大意:设 f( x ) 为 x 的数位之和,给出一个 n 和一个 k ,求 的最小 x ,若不存在,输出 -1 题目分析:因为 n 和 k 比较小,所以可以打表,当 k 为 0 的时候,显然是 r + 99...999 是最优的,...
2Sum of digits function in Zeckendorf base In order to prove a lower bound for theNth maximum order complexityof a sequence, we use a tool from [12, Proposition 3.1]. Lemma 1(12) Let\mathcal {S}be a sequence over\mathbb {F}_{2}of lengthn. Letkbe the length of the longest subseq...
