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,...
Reverse Integer之Java实现 一、题目 Given a 32-bit signed integer, reverse digits of an integer. Example 1: Input: 123 Output: 321 Example 2: Input: -123 Output: -321 Example 3: Input: 120 Output: 21 Note: Assume we are dealing with an environment which could only store integers within...
