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...
Did you notice that the reversed integer might overflow? Assume the input is a 32-bit integer, then the reverse of 1000000003 overflows. How should you handle such cases? Throw an exception? Good, but what if throwing an exception is not an option? You would then have to re-design the ...
为什么不直接&上0x00ff00ff，然后移动8位，最后再移动16位。是因为…reverse嘛，就是把组成Integer的...
