• codeforces 691B B. s-palindrome(水题)


    题目链接:

    B. s-palindrome

    题意:

    问给定的字符串是否是镜面对称;

    思路:

    直接看哪些字母是镜面对称的就行;

    AC代码:

    //#include <bits/stdc++.h>
    #include <iostream>
    #include <cstdio>
    #include <cstring>
    #include <algorithm>
    #include <cmath>
    
    using namespace std;
    
    #define For(i,j,n) for(int i=j;i<=n;i++)
    #define mst(ss,b) memset(ss,b,sizeof(ss));
    
    typedef  long long LL;
    
    template<class T> void read(T&num) {
        char CH; bool F=false;
        for(CH=getchar();CH<'0'||CH>'9';F= CH=='-',CH=getchar());
        for(num=0;CH>='0'&&CH<='9';num=num*10+CH-'0',CH=getchar());
        F && (num=-num);
    }
    int stk[70], tp;
    template<class T> inline void print(T p) {
        if(!p) { puts("0"); return; }
        while(p) stk[++ tp] = p%10, p/=10;
        while(tp) putchar(stk[tp--] + '0');
        putchar('
    ');
    }
    
    //const LL mod=1e9+7;

      if(x=='o'&&y=='o')return 1;
      if(x=='v'&&y=='v')return 1;
      //if(x=='m'&&y=='m')return 1;
      //if(x=='n'&&y=='n')return 1;
    //  if(x=='i'&&y=='i')return 1;
      if(x=='p'&&y=='q')return 1;
      if(x=='q'&&y=='p')return 1;
      if(x=='b'&&y=='d')return 1;
      if(x=='d'&&y=='b')return 1;
      return 0;
    }
    int main()

          int len=strlen(s);
          For(i,0,len-1)
          {
            str[len-i-1]=s[i];
          }
          For(i,0,len-1)
          {
            if(!check(s[i],str[i]))
            {
              //  cout<<s[i]<<" "<<str[i]<<endl;
              cout<<"NIE";
              return 0;
            }
          }
          cout<<"TAK";
            return 0;
