CodeForces - 691B s-palindrome (字符串,模拟)
Let's call a string "s-palindrome" if it is symmetric about the middle of the string. For example, the string "oHo" is "s-palindrome", but the string "aa" is not. The string "aa" is not "s-palindrome", because the second half of it is not a mirror reflection of the first half.
<center> English alphabet </center>You are given a string s. Check if the string is "s-palindrome".
InputThe only line contains the string s (1 ≤ |s| ≤ 1000) which consists of only English letters.
Print "TAK" if the string s is "s-palindrome" and "NIE" otherwise.
Input
oXoxoXo
Output
TAK
Input
bod
Output
TAK
Input
ER
Output
NIE
题意:判断一个字符串是否是对称的,是的话输出TAK,否则输出NIE。
首先要找出对称的字母,注意m、n两个字母不对称!
还要注意,b和d对称,p和q对称!
另外注意字符串对称的写法!
代码如下:
#include<bits/stdc++.h>
using namespace std;
int main()
{
char *s="AHIMOoTUVvWwXxY";
char a[1010];
bool flag=true;
scanf("%s",a);
for(int i=0;i<=strlen(a)/2;i++)
{
if(a[i]!=a[strlen(a)-i-1])
{
if((a[i]=='b'&&a[strlen(a)-i-1]=='d')||(a[i]=='d'&&a[strlen(a)-i-1]=='b'));
else if((a[i]=='p'&&a[strlen(a)-i-1]=='q')||(a[i]=='q'&&a[strlen(a)-i-1]=='p'));
else flag=false;
}
if((a[i]=='b'&&a[strlen(a)-i-1]=='d')||(a[i]=='d'&&a[strlen(a)-i-1]=='b'));
else if((a[i]=='p'&&a[strlen(a)-i-1]=='q')||(a[i]=='q'&&a[strlen(a)-i-1]=='p'));//这样写是为了能判断到中间的字母是否对称,但是没有中间字母的时候会错开
else if(strchr(s,a[i])==NULL)
{
flag=false;
}
}
if(flag==true)
{
printf("TAK\n");
}
else
{
printf("NIE\n");
}
}
