Example2: x = -123, return -321

class Solution {  
public:  
    int reverse(int x) {  
        int Answer=0;  
          
        if(-10 < x && x < 10) return x;    
        bool z = true;    
        if(x < 0) {z = false; x = -x;}    
      
        while(x!=0)  
        {  
            Answer=Answer*10+x%10;  
            x=x/10;  
        }  
        if(z==false)  
            Answer=-Answer;
