今天T2卡的我有点久(一开始的思考路线错了,手又冻的哆哆嗦嗦的,手速慢了哈哈(越来越菜了

AcWing 4800. 下一个

AcWing 4801. 强连通图
这题的思考方向就是循环,正循环和负循环,注意无论中间如何变幻,但是四个角的顺序一定要按正或负循环顺序排列,才能够实现到达任意点。
#include<bits/stdc++.h>
using namespace std;
typedef long long LL;
typedef pair<LL,LL> PII;
const LL MAXN=1e18,MINN=31;
const LL N=1e6+10,M=4002;
const double PI=3.1415926535;
#define endl '\n'
LL a[N];
int main()
{
cin.tie(0); cout.tie(0); ios::sync_with_stdio(false);
LL T=1;
//cin>>T;
while(T--)
{
LL n,m;
cin>>n>>m;
string s,c;
cin>>s>>c;
bool flag=true;
//<><> v^v^v^
if(s[0]=='<'&&s[n-1]=='>'&&c[0]=='v'&&c[m-1]=='^') ;
else if(s[0]=='>'&&s[n-1]=='<'&&c[0]=='^'&&c[m-1]=='v') ;
else flag=false;
if(flag==false) cout<<"NO"<<endl;
else cout<<"YES"<<endl;
}
return 0;
}
AcWing 4802. 金明的假期
忘记在哪里写过了这个的原题,所以很快就写完了,
就是每天和前面一个具有关联性,然后及时更改状态即可
#include<bits/stdc++.h>
using namespace std;
typedef long long LL;
typedef pair<LL,LL> PII;
const LL MAXN=1e18,MINN=31;
const LL N=1e6+10,M=4002;
const double PI=3.1415926535;
#define endl '\n'
LL a[N];
int main()
{
cin.tie(0); cout.tie(0); ios::sync_with_stdio(false);
LL T=1;
//cin>>T;
while(T--)
{
LL n;
cin>>n;
for(int i=1;i<=n;i++)
{
cin>>a[i];
}
LL sum=0;
for(int i=1;i<=n;i++)
{
if(a[i]==0) sum++;
else if(a[i]==3)
{
if(a[i-1]==2) a[i]=1;
else if(a[i-1]==1) a[i]=2;
}
else if(a[i]==1&&a[i-1]==1)
{
sum++;
a[i]=0;
}
else if(a[i]==2&&a[i-1]==2)
{
sum++;
a[i]=0;
}
}
cout<<sum<<endl;
}
return 0;
}
