A. Majestic 10
水题
AC代码:
N = int(input())
for i in range(N):
lst = list(map(int, input().strip().split()))
dc = 0
for j in range(3):
if lst[j] >= 10:
dc += 1
print(lst[0], lst[1], lst[2])
if dc == 0:
print('zilch')
elif dc == 1:
print('double')
elif dc == 2:
print('double-double')
elif dc == 3:
print('triple-double')
print()
B. Phoneme Palindromes
题意:判断是否是回文,另外会给定几组相对应得字符。
思路:用map存储一一对应的字母
AC代码:
#include<iostream>
#include<cstring>
#include<map>
#include<algorithm>
using namespace std;
#define ll long long
int main(){
ll n,p,q;
string ptr1;
char c1,c2;
cin>>n;
int num=1;
while(n--){
cin>>p;
map<char,char> mp;
for(int i=0;i<p;i++){
cin>>c1>>c2;
mp[c1]=c2;
}
cin>>q;
cout<<"Test case #"<<num<<":"<<endl;
num++;
for(int i=0;i<q;i++){//这是判断的
cin>>ptr1;
string pr=ptr1;//原始
string ptr2(ptr1.rbegin(),ptr1.rend());
if(ptr1==ptr2){
cout<<pr<<" "<<"YES"<<endl;
}else{
for(int j=0;j<ptr2.length();j++){
if(mp.count(ptr2[j])!=0){//表示存在
ptr2[j]=mp[ptr2[j]];
}
}
for(int j=0;j<ptr1.length();j++){
if(mp.count(ptr1[j])!=0){
ptr1[j]=mp[ptr1[j]];
}
}
if(ptr1==ptr2){
cout<<pr<<" "<<"YES"<<endl;
}else{
cout<<pr<<" "<<"NO"<<endl;
}
}
}
cout<<endl;
}
return 0;
}
C. Don't Break the Ice
题意:敲掉所给点的冰块,只有冰块所在的行或列完整冰块才存在,问有多少准备敲击的冰块是不存在的
思路:用数组记录每行每列冰块是否完整,如果敲击冰块的列和行都是不完整的则记录
AC代码:
#include<bits/stdc++.h>
#include<iostream>
#include<vector>
#include<queue>
#include<string>
#include<list>
#include<set>
#include<map>
#include<stack>
using namespace std;
typedef long long ll;
const int maxn = 300;
const ll mod = 1e9+7;
ll xnode[maxn];
ll ynode[maxn];
int main()
{
int N;
cin>>N;
{
for(int k=1;k<=N;k++)
{
memset(xnode,1,sizeof(xnode));
memset(ynode,1,sizeof(ynode));
int n,m;
cin>>n>>m;
int count = 0;
for(int i=0;i<m;i++)
{
int x,y;
cin>>x>>y;
if(xnode[x]==0&&ynode[y]==0)
{
count++;
}
else
{
xnode[x]=0;
ynode[y]=0;
}
}
cout<<"Strategy #"<<k<<": ";
cout<<count<<endl<<endl;
}
}
return 0;
}
D. Wildest Dreams
题意:给定每段CD的时间,和女儿是否在的时间段,问总共听女儿喜欢的CD多长时间
思路:直接模拟,注意:时间结束若女儿刚好离开,歌曲按顺序播放,不会从开头听,女儿离开,若歌曲没听完还会继续听:
AC代码:
#include<bits/stdc++.h>
#include<iostream>
#include<vector>
#include<queue>
#include<string>
#include<list>
#include<set>
#include<map>
#include<stack>
using namespace std;
typedef long long ll;
const int maxn = 150;
const ll mod = 1e9+7;
ll node[maxn];
map<char,char> mp;
int main()
{
int T;
cin>>T;
for(int K=1;K<=T;K++)
{
int k,t;
cin>>t>>k;
int Sum = 0;
for(int i=1;i<=t;i++)
{
cin>>node[i];
Sum+=node[i];
}
int n;
cin>>n;
printf("CD #%d:
",K);
while(n--)
{
int tsum = 0;
int d;
cin>>d;
int dt[150];
for(int i=1;i<=d;i++)
{
cin>>dt[i];
}
for(int i=1;i<=d;i++)
{
if(i%2==1)
{
tsum+=dt[i];
int tt = dt[i]%node[k];
if(tt==0) continue;
else
{
int ts = node[k]-tt;
if(i!=d)
{
if(dt[i+1]-ts>=0)
{
tsum+=ts;
dt[i+1]-=ts;
}
else
{
tsum+=dt[i+1];
dt[i+1]=0;
}
}
}
}
else
{
int t = dt[i]/Sum;
tsum+=t*node[k];
if(dt[i]%Sum!=0)
{
int ttt =dt[i]%Sum;
int tss = ttt-(Sum-node[k]);
if(tss>0) tsum+=tss;
}
}
}
cout<<tsum<<endl;
}
cout<<endl;
}
return 0;
}
E. Loopy Word Search
题意:给定字母方格和单词,找到单词首字母所在位置和方向
思路:暴力模拟;因为题意为通过首字母查找位置,可以记录字母方格中每个字母的所有位置,通过所给单词的首字母可以确定查找的范围,然后想上下左右四个方向查找符合题意得答案。
AC代码:
#include<bits/stdc++.h>
#include<iostream>
#include<vector>
#include<queue>
#include<string>
#include<list>
#include<set>
#include<map>
#include<stack>
using namespace std;
typedef long long ll;
const int maxn = 150;
const ll mod = 1e5+10;
char s[110][110];
typedef struct NODE{
int x;
int y;
}N;
vector<N> a[26];//记录字母网格中,每个字母所在得位置
int main()
{
int Q;
cin>>Q;
for(int K=1;K<=Q;K++)
{
for(int i=0;i<26;i++)
{
a[i].clear();
}
int n,m;
cin>>n>>m;
for(int i=0;i<n;i++)
{
for(int j=0;j<m;j++)
{
cin>>s[i][j];
N t;
t.x = i;
t.y = j;
a[s[i][j]-'A'].push_back(t);//按记录纪录位置
}
}
int p;
cin>>p;
printf("Word search puzzle #%d:
",K);
string q;
for(int i=0;i<p;i++)
{
cin>>q;
int count = a[q[0]-'A'].size();//记录单词首字母 在网格中出现得次数,再遍历
for(int j=0;j<count;j++)
{
N t = a[q[0]-'A'][j];
int flag = 1;
//四个方向遍历
//上
for(int e = (t.x-1+n)%n,f = 1;f<q.length();f++,e = (e-1+n)%n)
{
if(q[f]!=s[e][t.y])
{
flag = 0;
break;
}
}
if(flag == 1)
{
printf("U %d %d ",t.x+1,t.y+1);
cout<<q<<endl;
break;
}
flag = 1;
//下
for(int e =(t.x+1)%n,f=1;f<q.length();f++,e = (e+1)%n)
{

}
}

// 左
for(int e = (t.y-1+m)%m,f=1;f<q.length();f++,e = (e-1+m)%m)
{

{
flag = 0;
break;
}
}
if(flag==1)
{
printf("L %d %d ",t.x+1,t.y+1);
cout<<q<<endl;
break;
}
flag = 1;
//右
for(int e = (t.y+1)%m,f=1;f<q.length();f++,e = (e+1)%m)
{
if(q[f]!=s[t.x][e])
{

}
}
