Given a 32-bit signed integer, reverse digits of an integer. Example 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 the 32-bit signed integer ...
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 function (ie, add an extra parameter). 大意:题目...
class Solution { public: int reverse(int x) { if (x == 0) { return x; } bool negative = false; if (x < 0) { negative = true; x = 0 - x; } //检测该x是否已经溢出,溢出时直接返回0 int max = numeric_limits<int>::max(); if (x>max) return 0; //到此为止,x已经是非负...
Reverse digits of an integer. Example1: x = 123, return 321 Example2: x = -123, return -321 click to show spoilers. SOLUTION 1: 注意越界后返回0.先用long来计算,然后,把越界的处理掉。 View Code GITHUB: https://github.com/yuzhangcmu/LeetCode_algorithm/blob/master/math/Reverse.java...
Reverse digits of an integer. Example1: x = 123, return 321 Example2: x = -123, return -321 解题思路:将数字翻转并不难,可以转成String类型翻转,也可以逐位翻转,本题涉及到的主要是边界和溢出问题,使用Long或者BigInteger即可解决。 题目不难: JAVA实现如下: public class Solution { static public ...
