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')

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:

    cin>>T;
    for(int K=1;K<=T;K++)

        int Sum = 0;
        for(int i=1;i<=t;i++)

                            {
                                tsum+=ts;
                                dt[i+1]-=ts;
                            }

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:
