leetcode 测试用例无语，超过 int 界限要求返回 0。。。。。。。。。。。。。。

class Solution {
public:
    int reverse(int x) {
        long int  result=0;
        const int max = 0x7fffffff;  
        const int min = 0x80000000;   
            while(x!=0)
            {
                int pa=x%10;
                result=result*10+pa;
                if(result>max||result<min)
                {
                    
                    return 0;
                }
                
                x=x/10;
       
            }
      
        return result;
        
    }
};
