整型数n反转后的结果可能超出int类型所能表示最大范围,在Java中,int类型的包装类Integer定义了两个常量,MAX_VALUE(2147483647) 和MIN_VALUE(-2147483648),这两个常量指示了int型所能表示的数字范围,如果数字超过这个范围则不能正确的被表示,因此我们在改进代码的时候应该把溢出判定考虑进去,如果反转的过程中出现溢出,...

Output: 21 Note: Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−2^31, 2^31 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 二、解题思路: 1、定义一...
x/=10; if(ans>Integer.MAX_VALUE/10||(ans==Integer.MAX_VALUE/10&&temp>7)) return 0; if(ans<Integer.MIN_VALUE/10||(ans==Integer.MIN_VALUE/10&&temp<-8)) return 0; ans = ans*10+temp; } returnans; }
