最近做了一道题目: 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 intege
python2 中获取int最大值 import sys i = sys.maxint print i 但是在python3中,报错: AttributeError: module 'sys' has no attribute 'maxint' 看了官网文档后了解python3中没有maxint了,只有maxsize import sys i = sys.maxsize print(i) 官网说明文档:https://docs.python.org/3.1/whatsnew/3.0.html#i
来自:https://blog.csdn.net/qq_33611068/article/details/77369050 有这样一道题: 编程测试,遍历 0 到 int所能表示最大的正数,将消耗的时间打印. 下面是我的代码: int temp = 0; Date dt1 = new Date(); long begintime = dt1.getTime(); for(int i=0;i<=Integer.MAX_VALUE;i++){ temp = i; } Date dt2 = new D
