Codeforces Round #423 (Div. 2, rated, based on VK Cup Finals) A,B,C
A.题目链接:http://codeforces.com/contest/828/problem/A
解题思路:
直接暴力模拟
#include<bits/stdc++.h>
using namespace std; int main()
{
int m,d,s,i,num=,ans=,a[];
cin>>m>>d>>s;
for(i=;i<m;i++){
cin>>a[i];
if(a[i]==&&d)
d--;
else if(a[i]==&&d==&&s){
s--;num++;
}
else if(a[i]==&&s){
s--;
}
else if(a[i]==&&s==)
ans+=;
else if(a[i]==&&s==&&d==&&num)
num--;
else if(a[i]==&&s==&&d==&&num==)
ans++;
}
cout<<ans<<endl;
}
B.题目链接:http://codeforces.com/contest/828/problem/B
思路:
暴力
#include<bits/stdc++.h>
using namespace std;
#define inf 2e9
int main()
{
char mp[][];
int m,n,i,j,num=,ans=;
cin>>m>>n;
for(i=;i<=m;i++){
for(j=;j<=n;j++){
cin>>mp[i][j];
}
}
int maxi = -inf,maxj = -inf;
int mini = inf,minj=inf;
for(i=;i<=m;i++){
for(j=;j<=n;j++){
if(mp[i][j]=='B'){
if(i>maxi)
maxi = i;
if(i<mini)
mini = i;
if(j>maxj)
maxj = j;
if(j<minj)
minj = j;
num+=;
}
}
}
if(num==){
cout<<""<<endl;
return ;}
//cout<<num<<endl;
ans = max((maxi-mini+),(maxj - minj+));
//cout<<ans<<endl;
if(ans>m||ans>n)
cout<<"-1"<<endl;
else{
cout<<ans*ans-num<<endl;
}
return ;
}
C.题目链接:http://codeforces.com/contest/828/problem/C
解题思路:
暴力会超时,he前一区域比较,如果没有重合的进行替换操作,重合跳过;
#include<bits/stdc++.h>
using namespace std;
char s[];
int main()
{
int m,n,i,j,k,pre,x,maxx = -;
string s1;
ios::sync_with_stdio(false);
cin.tie();
cin>>m;
memset(s,'a',sizeof(s));
while(m--){
cin>>s1>>n;
int len = s1.size();
pre = -len;
for(i=;i<n;i++){
cin>>x;
for(k=max(,len-(x-pre));k<len;++k){
s[x+k-] = s1[k];
pre = x;
}
maxx = max(maxx,x+len-);
}
}
for(i=;i<maxx;i++)
cout<<s[i];
cout<<endl;
return ;
}
