题目链接:http://codeforces.com/problemset/problem/581/C 题目意思:给出 n 个数:a1, a2, ..., an (0 ≤ ai ≤ 100).给出值 k,可以把它加到任意的 ai 中,成为ai',对每个ai 加多少随你定,但是不能超过 100,k也不一定需要用完.现在需要求得最终的和⌊a1'⌋+⌊a2'⌋ + ... + ⌊an'⌋,使其最大. 比赛的时候真的很中规中矩地做,有那么一点思路:将 k 中的某些unit 加入到每个数中(而且优先需要处…

[链接] 我是链接,点我呀:) [题意] 在这里输入题意 [题解] 优先把不是10的倍数的变成10的倍数. (优先%10比较大的数字增加 如果k还有剩余. 剩下的数字都是10的倍数了. 那么先加哪一个都可以了. [代码] #include <bits/stdc++.h> using namespace std; const int N = 1e5; int a[N+10],n,k; int b[N+10]; int point = 0; int main() { ios::sync_with_…

Developing Skills CodeForces - 581C 你在玩一个游戏.你操作的角色有n个技能,每个技能都有一个等级ai.现在你有k次提升技能的机会(将其中某个技能提升一个等级,可以重复提升某一个等级).但技能的等级不能超过100.你可以不用用完全部的k次机会.已知角色的能力值=∑(ai/10),其中除法为向下取整的整除运算.问你如何分配这k次机会,才能使得角色的能力值最高.输出这个最大的能力值. Input 第一行两个整数n,k(1<=n<=10^5,0<=k<=…
