Determine whether an integer is a palindrome. Do this without extra space.
程序代碼：
bool isPalindrome(int x) { if(x<0) return false; else if(x<10) return true; else { int bit = (int)log10(x)+1; while(bit>0) { if(x%10!=x/((int)pow(10,bit-1))) { return false; } else { x = x%((int)pow(10,bit-1)); x/=10; bit -= 2; } } } return true;}新聞熱點
