By the answer:

#include <stdio.h>
#include<string.h>
int main() {
    int n, i,len,flag;
    char str[100];
    while (scanf("%d", &n)!=EOF) {
    	getchar();
    	while(n--){
    		gets(str);
    	    len=strlen(str);
    	    flag=0;
            for(i=0;i<len;i++){
        	    if(str[i]!=str[len-i-1]){       //回文串判断 
        		    flag++;
        		    break;
			    }
		    }
		    if(flag==0)
		        printf("yes\n");
		    else 
		        printf("no\n");
		}	
    }
    return 0;
