I think i have problem with read data

    while(n){
        n--;
        gets(s);
        if(s[0]==0){
            n++;
            continue;//empry line
        }
    //    printf("%s\n",s);
        i=0;
        for(j=0;j<3;j++){
            sscanf(&(s[i]),"%s",name);
            correct(name);
            team[n][j]=addname(name);
            i+=strlen(name);
            while(!(s[i]>='a' && s[i]<='z') && j<3)
                i++;
        }

    }
/find the first not small latin letter
void correct(char *s){
    int n=strlen(s);
    int j=0;
    for(int i=0;i<n;i++){
        if((s[i]>='a')&&(s[i]<='z')){
            s[j]=s[i];
            j++;
        }
        else{
            s[j]=0;
            return ;
        }
    }
}
I get WA 5.
