CF1186D - Vus the Cossack and Numbers
传送门：Problem - 1186D - Codeforces 输入的数要么向上取整，要么向下取整，那么设ans为负数的绝对值的和，sum为正数的和，对单一的负数向下取整于负数而言相当于ans++，同理正数向上取整sum++。 这里我们设ans1为ans的最小值即负数全部向上取整，ans2为ans最大值，sum1,sum2同理 由于题目保证CF1186 F. Vus the Cossack and a Graph

Vus the Cossack has two binary strings, that is, strings that consist only of “0” and “1”. We call these strings aa and bb. It is known that |b|≤|a||b|≤|a|, that is, the length of bb is at most the length of aa. The Cossack considers every substriCodeforces Round #571 (Div. 2)

1 /******* 2 http://codeforces.com/contest/1186/problem/C 3 题意：给2个0，1串，a串比b串长。 4 问a串有多少个和b串等长且不同的字符个数为偶数的串。 5 思路：首先比较出a中第一个串（记为a0）和b的不同字符个数（记为ans0）。然后a中第二个串（记为a1）将不在与b比较而是与a中第一个串比较题解 CF1186A 【Vus the Cossack and a Contest】
这题是入门难度的题目吧…… 根据题意可以得出，只有当\(m\)和\(k\)都大于等于\(n\)时，\(Vus\)才可以实现他的计划。 因此，我们不难得出以下\(AC\)代码： #include <iostream> #include <cstdio> #include <cstdlib> #include <cstring> #include <algorithm> #include <cmath> #includ
