整天自闭. A:有各种讨论方式.我按横坐标排了下然后讨论了下纵坐标单调和不单调两种情况.写了15min也就算了,谁能告诉我printf和cout输出不一样是咋回事啊?又调了10min啊?upd:突然想起来我好像define int long long了 #include<iostream> #include<cstdio> #include<cmath> #include<cstdlib> #include<cstring> #include&l…

明明多个几秒就能场上AK了.自闭. A:签到. #include<iostream> #include<cstdio> #include<cmath> #include<cstdlib> #include<cstring> #include<algorithm> using namespace std; #define ll long long ')) c=getchar();return c;} ?n:gcd(m,n%m);} in…

A 签到 #include<bits/stdc++.h> using namespace std; ],t[],ans; int main() { scanf("%d%d",&n,&m); ,x;i<=n;i++)scanf(]++; ,x;i<=m;i++)scanf(]++; ans=min(s[],t[])+min(s[],t[]); printf("%d",ans); } B 要求40次,而log(1e6)≍20,也就…

A:求出该行该列各有多少个比其小的取max,该行该列各有多少个比其大的取max,加起来即可. #include<iostream> #include<cstdio> #include<cmath> #include<cstdlib> #include<cstring> #include<algorithm> using namespace std; #define ll long long #define N 1010 char ge…

日常猝死. A:f[i]表示子树内包含根且可以继续向上延伸的路径的最大价值,统计答案考虑合并两条路径即可. #include<iostream> #include<cstdio> #include<cmath> #include<cstdlib> #include<cstring> #include<algorithm> using namespace std; #define ll long long #define N 30001…

嘿嘿嘿,第一篇文章,感觉代码可以缩起来简直不要太爽 打个div2发挥都这么差... 平均一题fail一次,还调不出错,自闭了 又一次跳A开B,又一次B傻逼错误调不出来 罚时上天,E还傻逼了..本来这场应该很前的,最后只苟在rated的人里面50 A. Chunga-Changa 随便做就行了,因为CF似乎不可以print("%d",0);于是WA了一个样例 #include<cstdio> #include<algorithm> #include<iost…

A:显然应该让未确定的大小尽量大.不知道写了啥就wa了一发. #include<iostream> #include<cstdio> #include<cmath> #include<cstdlib> #include<cstring> #include<algorithm> using namespace std; #define ll long long #define N 200010 #define inf 100000001…

Codeforces Round #528 (Div. 2)题解 A. Right-Left Cipher 很明显这道题按题意逆序解码即可 Code: # include <bits/stdc++.h> int main() { std::string s, t; std::cin >> s; int len = s.length(); int cnt = 0; for(int i = 0; i < len; i++) { t = t + s[((len + 1) / 2 +…
