代码：
class Solution {
public:
int reverse(int x) {
//当前值
int rev = 0;

		//被弹出的值
		int pop = 0;

		while(x!=0)
		{
			int pop = x%10;
			x = x/10;
			if(rev>INT_MAX/10||rev==INT_MAX/10&&pop > 7)
			{
				return 0;
			}

			if(rev < INT_MIN/10||rev == INT_MIN/10&&pop<-8)
			{
				return 0;
			}

			rev = rev*10 + pop;


		}

		return rev;
}

};

结果：
